If power dissipated in the `9 Omega` resistor in the resistor shown is `36 W`, the potential difference across the `2 Omega` resistor is

A

2 volt

B

4 volt

C

8 volt

D

10 volt

Text Solution

Verified by Experts

The correct Answer is:
D
`P= I^(2)R rArr I_(9) = sqrt(36)/9 =2A`
`I_(6) = 3a`
Total current `I = 2 + 3 = 5 A`
`V_(2Omega) = 5 xx 2 = 10` volt
