An alternating current of rms value 10 A is passed through a 12`Omega` resistor. The maximum potential difference across the resistor is

A

20 V

B

90 V

C

169.68 V

D

None of these

Verified by Experts

The correct Answer is:

C

`V_(rms) = I_(rms)R = 10 xx 2 = 120 V`
`V_(0) = sqrt(2) xx 120 = 169 . 68 V`
