1. What is the primary purpose of electrical grounding?
A. Increase voltage
B. Provide a safe path for fault current
C. Reduce wire size
D. Store electricity
Answer: B
Rationale: Grounding protects people and equipment by directing fault current safely to
earth.
2. What does NEC stand for?
A. National Electrical Company
B. National Electrical Code
C. National Energy Control
D. Network Electrical Circuit
Answer: B
Rationale: The NEC is the standard for safe electrical installation in the U.S.
3. What unit measures electrical current?
A. Volts
B. Ohms
C. Amperes
D. Watts
,Answer: C
Rationale: Current is measured in amperes (amps).
4. What does voltage represent?
A. Flow of electrons
B. Electrical pressure
C. Resistance
D. Power consumption
Answer: B
Rationale: Voltage is electrical potential or pressure.
5. What does resistance do in a circuit?
A. Increases current
B. Opposes current flow
C. Stores electricity
D. Generates voltage
Answer: B
Rationale: Resistance limits the flow of electrical current.
6. What is Ohm’s Law formula?
A. P = IV
B. V = IR
C. I = PR
D. R = VI
Answer: B
Rationale: Ohm’s Law states voltage equals current times resistance.
7. What does a circuit breaker do?
A. Increases voltage
B. Protects circuit by shutting off power during overload
, C. Stores electricity
D. Converts AC to DC
Answer: B
Rationale: It prevents damage from overloads or short circuits.
8. What is a short circuit?
A. Normal operation
B. Unintended low-resistance path
C. High voltage supply
D. Ground wire connection
Answer: B
Rationale: It causes excessive current flow.
9. What is the function of a fuse?
A. Store energy
B. Melt to break circuit during overload
C. Increase current
D. Convert voltage
Answer: B
Rationale: Fuses protect circuits by breaking when overheated.
10. What is alternating current (AC)?
A. Current flowing one direction only
B. Current that changes direction periodically
C. No current flow
D. Direct voltage
Answer: B
Rationale: AC reverses direction regularly.
11. What is direct current (DC)?
