1. What is the primary purpose of the National Electrical Code
(NEC)?
A. To design electrical systems
B. To provide safety standards for electrical installations
C. To calculate electrical loads
D. To certify electricians
Rationale: The NEC is primarily a safety standard, not a design
or certification guide.
Correct Answer: B
2. Which device protects against overloads and short circuits?
A. Transformer
B. Fuse or circuit breaker
C. Conduit
D. Switch
Rationale: Fuses and circuit breakers interrupt excessive
current flow.
Correct Answer: B
3. What does Ohm’s Law state?
,A. P = IV
B. V = IR
C. I = PR
D. R = VI
Rationale: Ohm’s Law defines voltage, current, and resistance
relationship.
Correct Answer: B
4. The unit of electrical power is:
A. Volt
B. Ampere
C. Watt
D. Ohm
Rationale: Power is measured in watts.
Correct Answer: C
5. A grounded conductor is typically identified by which color?
A. Green
B. White
C. Black
D. Red
Rationale: White is used for neutral/grounded conductors.
Correct Answer: B
,6. What is the function of a grounding conductor?
A. Carry load current
B. Provide a return path for normal current
C. Protect against fault current
D. Increase voltage

A. High resistance path
B. Low resistance unintended path
C. Normal load condition
D. Open circuit
Rationale: Short circuits create very low resistance paths.
Correct Answer: B
10. What device measures electrical current?
A. Voltmeter
B. Ohmmeter
C. Ammeter
D. Wattmeter
Rationale: Ammeters measure current flow.
Correct Answer: C
