Sample Odisha CHSE +2 VOC Field Technician Air Conditioner Practice Questions

Try these sample questions to review concepts for the Odisha CHSE +2 VOC Field Technician Air Conditioner exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1According to Ohm’s law, the current I through a resistive load equals:
A.Voltage times resistance (I = V × R)
B.Voltage divided by resistance (I = V / R)
C.Resistance divided by voltage (I = R / V)
D.Voltage plus resistance (I = V + R)
Explanation: Ohm’s law states I = V / R (or V = I × R) for a conductor at constant temperature. Field technicians use it when estimating current draw of AC loads from nameplate voltage and resistance.
2A room AC heater element of 24 Ω is supplied at 240 V. Approximate current is:
A.5 A
B.10 A
C.0.1 A
D.5760 A
Explanation: I = V / R = 240 / 24 = 10 A. Simple Ohm’s law calculation is common in electrical foundation units of the VOC Field Technician Air Conditioner syllabus.
3Power consumed by a purely resistive load equals:
A.P = V / I only
B.P = V × I (also I²R or V²/R)
C.P = R / I only
D.P = V + I + R
Explanation: Electrical power P = V × I. For a resistor, equivalently P = I²R = V²/R. AC technicians use power to size wiring, breakers, and understand energy use of compressors and heaters.
4A 1.5-ton split AC draws about 8 A at 230 V during steady cooling. Approximate electrical power is:
A.About 1.84 kW
B.About 18.4 W
C.About 230 kW
D.About 0.035 kW
Explanation: P = V × I = 230 × 8 = 1840 W ≈ 1.84 kW. This order of magnitude matches a typical mid-size residential split AC electrical input (not the same as refrigeration tonnage in isolation).
5Three equal 12 Ω resistors are connected in series across a supply. Total resistance is:
A.4 Ω
B.12 Ω
C.36 Ω
D.144 Ω
Explanation: Series resistances add: R_total = R1 + R2 + R3 = 12 + 12 + 12 = 36 Ω. Series addition is a core DC circuit skill in foundation electrical units.
6Two equal 30 Ω resistors are connected in parallel. Equivalent resistance is:
A.60 Ω
B.30 Ω
C.15 Ω
D.900 Ω
Explanation: For two equal resistors in parallel, R_eq = R/2 = 15 Ω. More generally 1/R_eq = 1/R1 + 1/R2. Parallel paths lower total resistance and raise total current for a given voltage.
7The SI unit of electrical energy is the joule (J). One kilowatt-hour (kWh) equals:
A.1 J
B.1000 J
C.3.6 × 10⁶ J
D.360 J
Explanation: 1 kWh = 1000 W × 3600 s = 3,600,000 J = 3.6 × 10⁶ J. Energy meters and electricity bills use kWh; understanding the conversion supports power-and-energy foundation topics.
8In a pure series circuit, which quantity is the same through every component?
A.Voltage drop
B.Current
C.Resistance
D.Power dissipated
Explanation: Series circuits have one current path, so the same current flows through each component. Voltage divides across series resistances; power can differ if resistances differ.
9Which statement correctly contrasts AC and DC for AC field work?
A.AC always has zero frequency; DC continuously reverses polarity
B.DC flows in one direction; AC periodically reverses direction
C.Mains room AC compressors always run only on pure battery DC
D.DC voltage is always higher than AC for the same wire size
Explanation: Direct current (DC) maintains a single polarity/direction; alternating current (AC) reverses periodically. Indian room AC units are typically single-phase AC mains powered, though internal electronics may use DC rails.
10The SI unit of electric current is the:
A.Volt (V)
B.Ohm (Ω)
C.Ampere (A)
D.Watt (W)
Explanation: Current is measured in amperes (A). Voltage is volts, resistance ohms, and power watts. Clamp meters used on AC service measure current in amperes without opening the circuit when used correctly.

About the Odisha CHSE +2 VOC Field Technician Air Conditioner Exam

Odisha CHSE +2 VOC Field Technician Air Conditioner: Suggested Study Strategy

1Alternate MCQ drills with short written definitions and cycle sketches—official theory is not pure MCQ.
2Practise real lab skills weekly: Ohm’s law calculations, clamp-meter amps, flare quality, vacuum pull-down, and filter/coil cleaning.
3Memorise the four major cycle components in flow order (compress → condense → expand → evaporate) before advanced diagnostics.
4Link pressures to temperatures for superheat/subcooling ideas; never charge by guesswork alone.
5For motors, contrast start vs run devices and thermal protection symptoms on hard-start compressors.
6Treat practical records, project work, and viva as mark-bearing: explain procedures, PPE, and instrument connections aloud.
7Use the official VOC unit lists as your checklist; this bank accelerates theory recall but does not replace CHSE practicals.

Frequently Asked Questions

Is the official CHSE Odisha Field Technician Air Conditioner exam pure multiple-choice?

No. Official vocational / integrated vocational assessment under CHSE uses theory plus practical, project, and often viva components. Some theory papers use mixed MCQ + short + long items (commonly around 50 theory marks under AHSE VOC patterns). This page’s 100 MCQs are an English study adaptation for underpinning theory and safe work judgment only.

What is the trade code / identity for this subject?

CHSE lists the subject as Higher Secondary (+2) VOC Electronics & Hardware — Field Technician Air Conditioner (trade code EAH on the AHSE programme). The official Class XI–XII curriculum PDF is hosted on chseodisha.nic.in. It is distinct from Field Technician Wireman Control Panel and from traditional EDA.

What topics are covered in CHSE VOC Field Technician Air Conditioner?

Class 11–12 units include foundation electrical, transformers and motors (including bimetallic relay and thermocouple themes), room AC refrigeration cycle and refrigerants awareness, window vs split installation, filters and PM, tools/testing (clamp meter, gauges, flaring, vacuum pump), advanced/IoT troubleshooting concepts, workplace safety, and light employability/green skills—matching the official VOC curriculum PDF.

How are marks structured for this vocational subject?

Assessment is mixed theory + practical/project/viva. Related VOC packaging often frames theory around 50 marks (employability + vocational) and practical blocks around 35 practical + 15 project, but always confirm the exact split and question pattern for your registration year on chseodisha.nic.in. Exam question counts vary by module.

What is the exam fee for this VOC subject?

There is no separate open stand-alone ‘air conditioner only’ marketplace fee quoted on this page. Fees are included in the Council’s Higher Secondary / vocational form-fill-up notification for the year and candidate category. See chseodisha.nic.in for the official circular.

Can this free MCQ bank replace practical, project, and viva preparation?

No. Practical skill evidence is essential (electrical measurement, flaring, vacuuming, gauge work, installation, PPE, refrigerant hygiene). Use these MCQs for theory drills and still complete labs, project records, and viva practice with your school.
