Exam Questions And Answers In Details
100% Verified Exam Highly
Recommendable For Grade A+
1. A 120V circuit supplies a load drawing 12 amps. What is the power
consumed?
A. 1,200 watts
B. 144 watts
C. 1,440 watts
D. 12 watts
Answer: C ✔
Rationale: Power is calculated using P = V × I = 120 × 12 = 1,440 watts.
2. According to NEC, what is the minimum number of general-purpose branch
circuits required in a dwelling kitchen?
A. 1
B. 2
C. 3
D. 4
Answer: B ✔
Rationale: NEC requires at least two 20-amp small appliance branch
circuits in kitchen areas.
3. What is the resistance of a circuit with 120V and 20A?
A. 6 ohms
, B. 240 ohms
C. 0.167 ohms
D. 2,400 ohms
Answer: A ✔
Rationale: R = V ÷ I = 120 ÷ 20 = 6 ohms.
4. Which device protects against overcurrent conditions?
A. Switch
B. Transformer
C. Circuit breaker
D. Conduit
Answer: C ✔
Rationale: Circuit breakers interrupt current flow during overload or short
circuit conditions.
5. What is the primary purpose of grounding in an electrical system?
A. Increase voltage
B. Provide a return path for normal current
C. Provide a low-resistance fault path to earth
D. Reduce conductor size
Answer: C ✔
Rationale: Grounding safely directs fault current to earth to prevent shock
hazards.
6. A 240V heater draws 10 amps. What is its power rating?
A. 2,400 watts
B. 24,000 watts
C. 240 watts
D. 1,200 watts
Answer: A ✔
Rationale: P = V × I = 240 × 10 = 2,400 watts.
7. What is the minimum cover requirement for PVC conduit under a
residential driveway?
, A. 6 inches
B. 12 inches
C. 18 inches

Answer: C ✔
Rationale: NEC typically requires 18 inches cover for PVC under driveways.
8. Which color insulation is typically used for grounded (neutral) conductors?
A. Green
B. White
C. Red
D. Black
Answer: B ✔
Rationale: White or gray insulation identifies grounded neutral
conductors.
9. A 1,000-watt load operates at 120V. What is the current?
A. 8.33 amps
B. 10 amps
C. 12 amps
D. 15 amps
Answer: A ✔
Rationale: I = P ÷ V = 1000 ÷ 120 = 8.33 amps.
10.What is the function of a GFCI?
A. Protect against overload
B. Protect against short circuits
C. Protect against ground faults
D. Increase circuit capacity
Answer: C ✔
Rationale: GFCI devices detect imbalance between hot and neutral and
trip during ground faults.
