Sample Odisha CHSE +2 Vocational EDA (Electrical Domestic Appliances) Practice Questions

Try these sample questions to review concepts for the Odisha CHSE +2 Vocational EDA (Electrical Domestic Appliances) exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1In basic electrical work for domestic appliances, electric current is best defined as:
A.The rate of flow of electric charge through a conductor
B.The force that always exists only in permanent magnets
C.The energy stored permanently in an open switch
D.The mechanical hardness of copper wire only
Explanation: Current is the rate of charge flow. Its SI unit is the ampere (A). Voltage is the potential difference that drives current; resistance opposes it.
2The SI unit of electrical resistance is the:
A.Ampere (A)
B.Ohm (Ω)
C.Volt (V)
D.Watt (W)
Explanation: Resistance is measured in ohms (Ω). Ampere is current, volt is potential difference, and watt is power.
3Ohm’s law for a metallic conductor at constant temperature states that:
A.Current is always independent of voltage
B.Resistance always equals zero in every circuit
C.Current is directly proportional to voltage (V = IR)
D.Power is always equal to resistance squared
Explanation: Ohm’s law: V = IR (or I = V/R). For many conductors at constant temperature, current is proportional to applied voltage.
4Three resistors of 6 Ω, 6 Ω and 6 Ω are connected in parallel. The equivalent resistance is:
A.18 Ω
B.6 Ω
C.0.5 Ω
D.2 Ω
Explanation: For equal resistors R in parallel, Req = R/n. Three 6 Ω in parallel → 6/3 = 2 Ω. Also 1/Req = 1/6 + 1/6 + 1/6 = 1/2.
5According to Kirchhoff’s Current Law (KCL) at a circuit node:
A.The algebraic sum of currents entering and leaving the node is zero
B.Voltage around every closed loop must always be infinite
C.Resistance of every branch must be identical
D.Current can only flow in open circuits
Explanation: KCL is charge conservation: sum of currents into a node equals sum leaving (algebraic sum zero). KVL is the loop voltage sum rule.
6Which factor increases the resistance of a uniform metallic conductor (other factors fixed)?
A.Increasing its cross-sectional area
B.Increasing its length
C.Using a better conductor material with lower resistivity
D.Cooling pure metals so that resistance always falls to zero at room temperature
Explanation: R = ρL/A. Resistance rises with length L and resistivity ρ, and falls as area A increases. Temperature also affects ρ for metals.
7A primary cell differs from a secondary cell mainly because a primary cell is:
A.Always exactly the same as a lead-acid automotive battery
B.Able to be recharged indefinitely with zero chemical change
C.Not designed for practical electrical recharging after discharge
D.Defined only as a transformer secondary winding
Explanation: Primary cells (e.g., many dry cells) are intended for one-way discharge and are not practically recharged. Secondary cells (lead-acid, etc.) are rechargeable.
8While preparing electrolyte for a lead-acid cell, the safe practice is to:
A.Pour water rapidly into pure concentrated sulphuric acid
B.Use only pure mercury as the electrolyte liquid
C.Ignore specific gravity because it never changes with charge state
D.Always add acid slowly to water, never water into concentrated acid
Explanation: Dilution of sulphuric acid is strongly exothermic. Adding acid to water (slowly, with stirring) is the standard safety rule. Specific gravity with a hydrometer indicates state of charge.
9Two identical capacitors each of capacitance C connected in series have equivalent capacitance:
A.C/2
B.2C
C.C
D.C²
Explanation: Series capacitors: 1/Ceq = 1/C + 1/C → Ceq = C/2. Parallel equal capacitors give 2C.
10The energy stored in a capacitor of capacitance C charged to voltage V is:
A.CV
B.(1/2)CV²
C.C/V
D.2C/V²
Explanation: Stored electrostatic energy U = (1/2)CV² (also = (1/2)QV = Q²/(2C)).

About the Odisha CHSE +2 Vocational EDA (Electrical Domestic Appliances) Exam

Odisha CHSE Higher Secondary Vocational Repair and Maintenance of Electrical Domestic Appliances (EDA) is the official +2 vocational trade subject listed in the Council’s Engineering-area vocational catalog (Part-1-1 Electrical Domestic Appliances). It develops electrician/appliance-service underpinning knowledge: circuit fundamentals, cells and capacitors, heating and lighting, AC/polyphase theory, insulating materials and soldering, measuring instruments, domestic wiring and earthing, transformers and motors, and repair of common appliances (heaters, irons, stoves, geysers, kettles, fans, mixers, washers, coolers, vacuum cleaners, emergency lights, stabilizers, hand drills) with occupational safety. 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, wiring practice, machine/appliance dismantling, 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 EDA (Electrical Domestic Appliances): Suggested Study Strategy

1Alternate MCQ drills with short written definitions and circuit diagrams—official theory is not pure MCQ.
2Practise real lab skills weekly: Ohm’s law verification, series-parallel wiring, megger IR checks, and polarity tests.
3Memorise star vs delta line/phase relations and V = IR / P = VI forms before tackling motor and appliance faults.
4Draw the domestic wiring path (DB → MCB/ELCB → switch → load → neutral/earth) and pipe vs plate earthing sketches.
5For appliances, link symptoms to stages: no heat → open path; trips protection → short/earth leakage; hums no start → capacitor/mechanics.
6Never dry-run immersion heaters; always isolate supply before geyser or motor repairs.
7Treat practical records and viva as mark-bearing: explain procedures, safety, and instrument connections aloud.
8Use official Part-1-1 unit lists as your checklist; this bank accelerates theory recall but does not replace CHSE practicals.
