The power dissipation in each of four parallel branches is 1.2 W. The total power dissipation is________________?
Correct answer: B. 4.8 W
- A. 1.2 W
- B. 4.8 W
- C. 0.3 W
- D. 12 W
Explanation
Power in parallel branches is additive because the source supplies the sum of the branch powers. Hence, total power = 4 × 1.2 = 4.8 W.
