1. Ohm’s Law states that current is equal to voltage divided
by resistance. Which formula represents this?
A. V = I × R
B. C. I = V / R
C. P = V × I
D. R = V − I
Rationale: Ohm’s Law defines the relationship between
volts, amps, and ohms.
2. Which unit measures electrical resistance?
A. Volts
B. Amps
C. D. Ohms
D. Watts
Rationale: Resistance is measured in ohms (Ω).
3. If voltage increases while resistance stays the same,
current will:
A. Decrease
B. C. Increase
C. Stay the same
, D. Go to zero
Rationale: Current is directly proportional to voltage.
4. What is the power in a circuit with 10 A and 120 V?
A. 100 W
B. C. 1,200 W
C. 120 W
D. 12 W
Rationale: Power (P) = V × I.
5. Capacitance is a property that:
A. Opposes current flow
B. C. Stores electrical energy
C. Measures current
D. Converts AC to DC
Rationale: Capacitors store electric charge.
6. Inductive reactance increases when:
A. Frequency decreases
B. Voltage increases
C. D. Frequency increases
D. Resistance decreases
Rationale: Inductive reactance is proportional to
frequency.
7. A series circuit has:
A. Multiple paths
B. C. One path
C. No current
, D. Variable voltage
Rationale: Series circuits have one path for current.
8. Parallel circuits provide:
A. A single path
B. C. Multiple paths for current
C. No voltage
D. Short circuits only
Rationale: Each branch in parallel has its own path.
9. True power is measured in:
A. Volts
B. C. Watts
C. VARs
D. Ohms
Rationale: True power is actual consumed power.
10. A kilowatt equals how many watts?
A. 10
B. 100
C. D. 1,000
D. 10,000
Rationale: “kilo” equals 1,000.
11. AC stands for:
A. Active Current
B. C. Alternating Current
C. Absolute Charge
D. Ampere Capacity
Rationale: AC alternates direction.
