A resistor and an inductor are conneted ...

A resistor and an inductor are conneted in sires to a `220 "volt" AC` supply. When measured with an `AC` is `123` volts. Then the potential difference across the terminals of the inductor is

A

`88` volt

B

`352` volt

C

`176` volt

D

`sqrt(220xx132)` volt

Text Solution

Verified by Experts

The correct Answer is:
C
`V_(L)=sqrt(220^(2)-132^(2))`volt
`=sqrt((220+132)(220-132))`
`=sqrt(352xx88) "volt" =sqrt(30967) "volt"=176` volts.
