Sample Odisha CHSE +2 Vocational Mobile Technology Practice Questions

Try these sample questions to review concepts for the Odisha CHSE +2 Vocational Mobile Technology 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 relationship among voltage (V), current (I), and resistance (R) is best written as:
A.V = I × R
B.V = I / R
C.V = R / I
D.V = I + R
Explanation: Ohm’s law states that voltage across a resistive element equals current times resistance (V = IR). This foundational relation is Unit-I content in the CHSE Mobile Technology electrical basics unit.
2In mobile-repair electrical theory, a good conductor is a material that:
A.Allows electric charge to flow easily because it has many free electrons
B.Always blocks current completely under all voltages
C.Is defined only by mechanical hardness, not free electrons
D.Must be a pure insulator doped with rare-earth metals
Explanation: Conductors (copper, aluminium, silver, etc.) have many free electrons that move under an applied field, so current flows easily—standard Unit-I conductors content.
3Which pair correctly matches material class to electrical role?
A.Copper track — conductor; plastic housing / glass — insulator
B.Glass — preferred high-current bus bar
C.Rubber — best chassis ground strap metal
D.Mica — preferred flexible mains live cord
Explanation: Copper (and similar metals) conduct; plastics, glass, rubber, and mica typically insulate. Matching material class to role is core electrical-basics skill for phone work.
4Semiconductors used in mobile electronics are materials whose conductivity is generally:
A.Between that of good conductors and good insulators, and can be controlled by doping and bias
B.Always higher than pure copper at room temperature
C.Exactly zero under all conditions
D.Identical to superconductors at room temperature
Explanation: Semiconductors (Si, Ge, GaAs, etc.) sit between conductors and insulators; doping and applied bias control carrier density—Unit-I semiconductor framing.
5Two equal resistors R each are connected in series. The equivalent resistance is:
A.2R
B.R/2
C.R
D.4R
Explanation: Series resistances add: Req = R + R = 2R. Series combinations raise total resistance—classic Ohm’s-law extension in MT Unit-I.
6Two equal resistors R each are connected in parallel. The equivalent resistance is:
A.R/2
B.2R
C.R
D.0
Explanation: For two equal resistors in parallel, Req = R/2. Parallel paths reduce equivalent resistance.
7Electrical power delivered to a resistive load is commonly expressed as:
A.P = V × I (also P = I²R or P = V²/R)
B.P = V / I only, with no other forms
C.P = V + I
D.P = R − I
Explanation: Power is the product of voltage and current; for a resistor, P = I²R = V²/R also hold. Work–power–energy is explicit in MT Unit-I.
8If a 12 V DC rail supplies 0.5 A to a load continuously, the power drawn is:
A.6 W
B.24 W
C.0.5 W
D.12.5 W
Explanation: P = V × I = 12 × 0.5 = 6 W. Simple power problems appear under work–power–energy in the MT electrical unit.
9Energy consumed by an appliance is most directly related to:
A.Power × time (e.g., watt-hours or kilowatt-hours on a bill)
B.Voltage alone with no time factor
C.Resistance alone with no current or time
D.Only the colour of the appliance housing
Explanation: Energy = power × time. Monthly billing and energy-consumption problems in Unit-I use this idea (kWh on utility bills).
10In DC circuits used for phone rails, current conventionally flows:
A.From the more positive potential toward the more negative potential through the external circuit
B.Only through insulators, never through copper
C.Without any relationship to potential difference
D.From ground into open air as static only
Explanation: Conventional current is defined from higher to lower potential through the external load path. Understanding potential difference underpins power-rail troubleshooting.

About the Odisha CHSE +2 Vocational Mobile Technology Exam

Odisha CHSE Higher Secondary Vocational Mobile Technology (MT / MTV) is the official +2 vocational trade subject listed in the Council’s Mobile Technology syllabus PDF and AHSE examination programmes. It develops mobile-service underpinning knowledge: electrical basics (Ohm’s law, power/energy), SMD component identification and testing, soldering and rework tools, phone dismantling/assembly, section-level troubleshooting (network, audio, charging, dead sets), internal blocks (baseband, regulators, memory, display, SIM, antenna path), batteries and chargers, smartphone and tablet repair concepts, Android/iOS software-tool orientation, and related Paper-II topics in optical fibre and telephone exchange/broadband. Official assessment is mixed theory and substantial practical skill evidence. The free 100 MCQs on this page are an English-language multiple-choice study adaptation for theory and diagnostic judgment only—they are not a substitute for lab work, SMD practice, instrument use, practical records, viva, or the official written paper format.

Exam sponsor: Council of Higher Secondary Education, Odisha (CHSE Odisha). The requirements and fees below concern the certification or admission exam, separate from our free practice resources.

Odisha CHSE +2 Vocational Mobile Technology: Suggested Study Strategy

1Alternate MCQ drills with short written definitions and block diagrams—official theory is not pure MCQ.
2Practise real lab skills weekly: SMD identification, multimeter continuity/diode checks, soldering/desoldering, and safe phone dismantling.
3Memorise Ohm’s law forms and series/parallel rules; work simple power and energy examples before memorising only words.
4Draw a phone block path (antenna → RF/network → baseband → power/display/audio) before drilling section-fault MCQs.
5For dead phones, always reason power and charging first; for network faults, think antenna/PFO/RF path before random IC swaps.
6Treat ESD as non-negotiable: wrist strap, grounded mat, and careful handling of static-sensitive parts and BGA packages.
7Treat practical records and viva as mark-bearing: explain procedures, safety, and instrument connections aloud.
8Use the official Mobile-Technology.pdf unit lists as your checklist; this bank accelerates theory recall but does not replace CHSE practicals.
