Resistors of 6 Ω and 3 Ω are in parallel across an ideal 6 V battery. What are the total current and power?
A3 A and 12 W
B2 A and 12 W
C1 A and 6 W
D3 A and 18 W
Answer & Solution
Correct answer: D. 3 A and 18 W
The branch currents are 1 A and 2 A, so the total is 3 A and the power is 6 × 3 = 18 W.
