1Under Brazilian Federal Law No. 6,496/1977 and the CONFEA/CREA system regulations, what is the primary legal and professional purpose of the Technical Responsibility Note (Anotação de Responsabilidade Técnica - ART)?
A.It legally defines the professional responsible for an engineering service or project, registers technical authorship, and forms the basis for the professional's technical collection (Acervo Técnico).
B.It serves exclusively as a municipal tax receipt (ISS) and commercial billing authorization for engineering consulting firms.
C.It functions as an automatic environmental licensing clearance issued directly by the regional engineering council to bypass IBAMA review.
D.It transfers all civil, labor, and criminal liabilities of an engineering failure entirely to the regional CREA autarchy.
Explanation: Federal Law No. 6,496/1977 instituted the ART as the mandatory legal instrument that defines the civil and technical responsibility of the engineer for any technical work or service. It guarantees authorship rights, provides consumer protection by identifying the qualified professional, and serves as the official source to build the engineer's Technical Collection Certificate (Certidão de Acervo Técnico - CAT).
2Brazilian Regulatory Standard NR-10 (Safety in Electrical Installations and Services) defines safety perimeters around live electrical parts. How are the Risk Zone (Zona de Risco - ZR) and Controlled Zone (Zona Controlada - ZC) defined regarding access and intervention?
A.The Risk Zone is the space adjacent to live parts accessible only by authorized professionals using appropriate personal protective equipment and procedures; the Controlled Zone is an outer buffer restricted to authorized personnel.
B.The Risk Zone is open to general maintenance staff provided they wear standard cotton overalls, whereas the Controlled Zone requires full dielectric isolation.
C.The Controlled Zone surrounds de-energized and grounded circuits only, while the Risk Zone applies exclusively to high-voltage transmission lines exceeding 230 kV.
D.Both Risk and Controlled zones allow unrestricted pedestrian access if warning tape and general caution signage are displayed on the floor.
Explanation: According to Annex II of NR-10, the Risk Zone (ZR) is the innermost boundary immediately surrounding energized parts, where work is considered equivalent to live-line intervention requiring specialized authorization and PPE. The Controlled Zone (ZC) is the surrounding boundary between the Free Zone and the Risk Zone, accessible strictly to authorized workers.
3According to NR-10 item 10.5.1, what is the mandatory chronological sequence of procedures required to formally consider an electrical installation de-energized before maintenance?
A.1) Disconnection; 2) Lockout and tagout; 3) Verification of voltage absence; 4) Installation of temporary grounding; 5) Protection of adjacent live elements; 6) Signage and signaling.
B.1) Verification of voltage absence; 2) Disconnection; 3) Signage; 4) Installation of temporary grounding; 5) Lockout; 6) Protection of adjacent elements.
C.1) Installation of temporary grounding; 2) Disconnection; 3) Lockout; 4) Verification of voltage absence; 5) Signage; 6) Protection of adjacent elements.
D.1) Lockout and tagout; 2) Disconnection; 3) Protection of adjacent live elements; 4) Verification of voltage absence; 5) Signage; 6) Temporary grounding.
Explanation: NR-10 item 10.5.1 explicitly mandates the exact sequence: I - seccionamento (disconnection); II - impedimento de reenergização (lockout/tagout); III - constatação da ausência de tensão (voltage absence check); IV - instalação de aterramento temporário com equipotencialização dos condutores (temporary grounding); V - proteção dos elementos energizados existentes na zona controlada (protection of adjacent energized parts); VI - instalação da sinalização de impedimento (safety signaling).
4In the context of the Brazilian National Environmental Policy (PNMA - Law 6.938/1981) and CONAMA Resolution 001/1986, which statement correctly evaluates the environmental impact assessment for major power generation projects?
A.Hydroelectric power plants with significant reservoir flooding require an Environmental Impact Study and Report (EIA/RIMA) with public hearings, whereas utility-scale solar and wind projects undergo specific simplified or regular licensing based on local ecosystem sensitivity.
B.All renewable energy plants (solar, wind, and hydro under 50 MW) are completely exempt from any state or federal environmental licensing in Brazil.
C.The EIA/RIMA is a confidential document prepared solely for corporate board approval and is legally prohibited from being accessed by affected local communities.
D.Environmental licensing in Brazil consists of a single permanent permit issued prior to construction that eliminates the need for installation or operating licenses.
Explanation: CONAMA Resolution 001/1986 requires an EIA/RIMA for hydroelectric projects above 10 MW and large infrastructure. The RIMA must be presented in public hearings. Wind and solar projects require environmental licensing through state environmental agencies (OEMAs) following specific simplified or standard tiered processes (LP, LI, LO).
5The Brazilian National Interconnected System (SIN), operated by the ONS, features a hydrothermal power matrix with a high penetration of non-dispatchable variable renewables (wind and solar). What is the operational purpose of the Marginal Cost of Operation (CMO) in the centralized economic dispatch?
A.It represents the expected cost to supply one additional megawatt-hour of demand over the optimization horizon, balancing immediate thermal fuel costs against future water storage value.
B.It establishes a fixed government tax levied on all renewable generators to subsidize coal imports.
C.It dictates the retail flat tariff paid by residential low-voltage consumers under the regulated market (ACR).
D.It sets the penalty fine charged to transmission concessionaires whenever line losses exceed 2%.
Explanation: The CMO (Custo Marginal de Operação) is calculated by computational optimization models (NEWAVE, DECOMP, DESSEM) used by ONS and CCEE. It reflects the trade-off between generating thermal energy today (incurring direct fuel costs) versus using stored reservoir water today (which carries the opportunity cost of potential future thermal generation or deficit if water runs out).
6Under the Brazilian Legal Framework for Distributed Generation (Law No. 14,300/2022), what key modification was introduced regarding the compensation of grid usage tariffs for new micro and mini distributed generation units?
A.Gradual phase-in of payment for the distribution grid component (Tarifa de Uso do Sistema de Distribuição - TUSD Fio B) on energy injected and compensated through the public grid.
B.Total prohibition of net metering credits for residential rooftop photovoltaic systems exceeding 3 kW.
C.Mandatory conversion of all distributed solar generators into commercial generation concessionaires subject to centralized ONS dispatch.
D.Exemption of all industrial auto-producers from paying for transmission wire costs (TUST) for 50 years.
Explanation: Law 14,300/2022 established a transition rule for GD units connecting after the protocol deadline, requiring them to gradually pay the TUSD Fio B component (remunerating the local distribution wire infrastructure) on injected energy, moving away from the 100% volumetric net metering model of ANEEL REN 482/2012.
7According to the CONFEA Code of Professional Ethics (Resolution No. 1,002/2002), which of the following practices constitutes a direct ethical violation in the exercise of engineering?
A.Signing technical documents, projects, or technical responsibility notes (ART) for works or services that were not personally designed, directed, or supervised by the engineer.
B.Refusing a technical assignment due to a conflict of interest or lack of technical qualification in a specific domain.
C.Publishing scientific papers and peer-reviewed technical findings in international academic journals.
D.Providing continuing education and safety training to technical subordinates at a construction site.
Explanation: CONFEA Resolution 1002/2002 explicitly defines 'acobertamento'—signing studies, drawings, or ARTs for technical work without direct personal execution or supervision—as a severe ethical transgression and illegal practice.
8An industrial plant in Brazil installs an on-site 2.0 MW solar photovoltaic system that generates 3,600 MWh of clean electricity annually, offsetting grid electricity consumption. If the official average grid emission factor for the National Interconnected System (SIN) in that year is 0.080 tCO2e/MWh, what is the annual greenhouse gas emissions reduction achieved by the project?
A.288 tCO2e
B.450 tCO2e
C.2,880 tCO2e
D.28.8 tCO2e
Explanation: The avoided greenhouse gas emissions are calculated by multiplying annual energy generation by the grid emission factor: Delta E_GHG = 3,600 MWh * 0.080 tCO2e/MWh = 288 tCO2e per year.
9An electrical engineer conducts an energy efficiency retrofit in a commercial facility, replacing 500 legacy fluorescent fixtures (80 W each, including ballast) with high-efficiency LED luminaires (32 W each). The system operates 4,000 hours per year, and the average electricity tariff is R$ 0.75 per kWh. What is the total annual financial savings generated by this retrofit?
A.R$ 72,000.00
B.R$ 96,000.00
C.R$ 48,000.00
D.R$ 144,000.00
Explanation: Power reduction per fixture = 80 W - 32 W = 48 W = 0.048 kW. Total power reduction for 500 fixtures = 500 * 0.048 kW = 24 kW. Annual energy saved = 24 kW * 4,000 h = 96,000 kWh. Annual financial savings = 96,000 kWh * R$ 0.75/kWh = R$ 72,000.00.
10In medium-voltage switchgear safety engineering (NR-10 / IEEE 1584), what does the Arc Thermal Performance Value (ATPV) rating of personal protective equipment (PPE) signify?
A.The incident thermal energy on a fabric or material that results in a 50% probability of causing a second-degree skin burn through the material, expressed in cal/cm².
B.The maximum AC dielectric breakdown voltage of the insulating safety helmet under dry laboratory test conditions.
C.The maximum acoustic decibel level generated during an explosive electrical short circuit inside an arc-resistant switchgear enclosure.
D.The mechanical tensile breaking strength of the worker's safety harness during confined space entry.
Explanation: ATPV (expressed in cal/cm² or J/cm²) is the standard thermal performance metric defining the incident energy level where there is a 50% probability that heat transfer through the protective garment will cause a second-degree burn (Stoll curve threshold).

ENADE Engenharia Elétrica Study Tips from Top Performers

1Read Portaria INEP nº 164 of 14 April 2026: it lists the 19 objetos de conhecimento that define the Componente Específico, and it replaced the pre-2026 guidance.
2Be fluent with per-unit conversion between machine and system bases; it underpins most fault and power-flow questions.
3Practise symmetrical-component fault analysis: series-connected sequence networks for single line-to-ground faults, parallel for line-to-line and double line-to-ground.
4Know NBR 5410 numerically, not just conceptually: ampacity correction factors for temperature and grouping, voltage-drop limits and the 30 mA RCD requirement.
5Work converter problems end to end: duty-cycle relationships for buck, boost and buck-boost, inductor ripple, and inverter output voltage in the linear SPWM region.
6Drill classical control: Routh-Hurwitz gain ranges, root-locus asymptotes and centroid, second-order overshoot and Ziegler-Nichols PID settings.
7Do not neglect the 15-item Formação Geral block; it is not engineering-specific and draws on the transversal themes listed in Portaria INEP nº 154/2026.

Frequently Asked Questions

What is the official structure of the 2026 ENADE Engenharia Elétrica exam?

Under Edital INEP nº 61/2026 and Portaria INEP nº 164/2026, the paper runs for 4 hours and contains 46 items: 15 Formação Geral multiple-choice questions common to every course in the cycle, plus a Componente Específico of 30 multiple-choice questions and 1 discursive question. The 2026 sitting is on 29 November 2026.

Is there a pass mark for ENADE?

No. ENADE produces no individual pass or fail. It is a mandatory curricular component, so a graduating student who is registered and fails to sit it cannot graduate, but the scores are used to build the course's Conceito Enade on a 1 to 5 scale and feed the CPC and IGC quality indicators for the programme and institution.

Who has to sit ENADE Engenharia Elétrica?

Graduating (concluinte) students of Bacharelado em Engenharia Elétrica whose institution registers them through the Sistema Enade. Entering (ingressante) students are no longer required to sit the paper but must complete the Questionário do Estudante Ingressante to stay in good standing.

Is there a fee to take ENADE?

No. ENADE is free for students. Registration is handled by the higher education institution (IES) through INEP's Sistema Enade, not by the student individually.

How does ENADE differ from CREA registration?

ENADE is an academic assessment run by INEP/MEC to measure course quality. Professional registration with the Conselho Regional de Engenharia e Agronomia (CREA/CONFEA) is the separate legal licence, obtained after graduation, that allows you to practise engineering in Brazil.

Do these practice questions match the official exam format?

Not exactly. The official exam is written and answered in Portuguese and includes a discursive item plus a broad Formação Geral block on transversal themes such as human rights, climate change and social inclusion. This bank is an English-language multiple-choice study adaptation built from the official objetos de conhecimento; it is a study aid, not an official translation or a format simulation.
