In a `LCR` circuit the `P.D` between the terminals of the inductance is `60V`, between the terminals of the capacitor is `30V` and that between the terminals of resistance is `40V`. The supply voltage will be equal to......

A

`50V`

B

`70V`

C

`130V`

D

`10V`

Text Solution

Verified by Experts

The correct Answer is:
A
`V=sqrt(V_(R)^(2)+(V_(L)-V_(C))^(2))=sqrt((40)^(2)+(60-30)^(2))=50 V`
