1. What is the basic unit of electrical current?
A. Volt
B. Ohm
C. Ampere
D. Watt
Correct Answer: C. Ampere
Rationale: The ampere (amp) is the standard unit used to
measure electric current.
2. Which instrument is primarily used to measure voltage?
A. Ammeter
B. Voltmeter
C. Ohmmeter
D. Wattmeter
Correct Answer: B. Voltmeter
Rationale: A voltmeter measures the electrical potential
difference between two points.
3. What does Ohm’s Law state?
A. P = VI
B. V = IR
,C. I = PR
D. R = VI
Correct Answer: B. V = IR
Rationale: Ohm’s Law establishes the relationship between
voltage, current, and resistance.
4. A 120-volt circuit has a resistance of 20 ohms. What current
flows through the circuit?
A. 4 A
B. 6 A
C. 8 A
D. 10 A
Correct Answer: B. 6 A
Rationale: I = V/R = 120/20 = 6 amperes.
5. What is the primary purpose of a circuit breaker?
A. Increase voltage
B. Store electrical energy
C. Protect conductors from overcurrent
D. Reduce resistance
Correct Answer: C. Protect conductors from overcurrent
Rationale: Circuit breakers open a circuit when excessive
current occurs.
6. Which conductor normally carries current back to the
source in a standard single-phase circuit?
A. Grounding electrode conductor
B. Neutral conductor
,C. Bonding jumper
D. Equipment grounding conductor
Correct Answer: B. Neutral conductor
Rationale: The neutral is the grounded circuit conductor that
normally provides the return path for unbalanced current.
7. What is the purpose of an equipment grounding conductor?
A. Carry normal load current
B. Increase circuit voltage
C. Provide a low-impedance fault-current path
D. Reduce power consumption
Correct Answer: C. Provide a low-impedance fault-current path
Rationale: The equipment grounding conductor helps facilitate
operation of the overcurrent protective device during a fault.
8. Which material is commonly used for electrical conductors?
A. Copper
B. Glass
C. Rubber
D. Concrete
Correct Answer: A. Copper
Rationale: Copper has excellent electrical conductivity and is
widely used for wiring.
9. What is the electrical unit of resistance?
A. Watt
B. Volt
, C. Ohm
D. Ampere
Correct Answer: C. Ohm
Rationale: Resistance is measured in ohms.
10. What happens to current when resistance increases while
voltage remains constant?
A. Current increases
B. Current decreases
C. Current becomes zero automatically
D. Voltage increases
Correct Answer: B. Current decreases
Rationale: According to I = V/R, current decreases as resistance
increases at constant voltage.
11. What is the formula for electrical power?
A. P = VI
B. P = V/R
C. P = I/R
D. P = R/V
Correct Answer: A. P = VI
Rationale: Electrical power in watts equals voltage multiplied by
current.
12. A 120-volt load draws 5 amperes. What is its power
consumption?
A. 24 W
B. 125 W
