Type: MCQ-numerical-Medium-Class 12

If power dissipated in the 9 Ω resistor in the circuit shown is 36 Watt, the potential difference across the 2 Ω resistor is

Question diagram

A

2 Volt

B

4 Volt

C

8 Volt

D

10 Volt

Correct Answer

Option D

Detailed Explanation

Current in 9Ω is 2A, so that in 6Ω is 3A. Total current is 2 + 3 = 5A. Potential drop = 5 × 2 = 10V
