In an A.C. series circuit of L-R voltage applied is 220 V, if the potential difference across two ends on inductor is 176 V then the potential difference across two ends of the resistance will be ……

A

44 V

B

110 V

C

132 V

D

220 V

Text Solution

Verified by Experts

The correct Answer is:
C

Using Kirchoff.s second law for closed loop,
`V^2=V_R^2+V_L^2`
`therefore V_R^2=V^2-V_L^2`
`=(220)^2 - (176)^2`
=48400-30976 = 17424
`therefore V_R`= 132 V
