1. Ohm’s Law

A circuit has 10 V across a 5 Ω resistor. Current is:
A. 0.5 A
B. 2 A
C. 5 A
D. 50 A

Answer: B
Rationale: I = V/R = 10/5 = 2 A



2. Power Formula

Electrical power in a DC circuit is:
A. P = VI
B. P = V/I
C. P = I/R
D. P = VR

Answer: A
Rationale: Power equals voltage times current.



3. Series Resistance

,Three resistors 2Ω, 3Ω, 5Ω in series equal:
A. 10Ω
B. 30Ω
C. 1Ω
D. 15Ω

Answer: A
Rationale: Series resistances add directly.
