Calculate the potential across the capacitance if 50 V AC is applied across RC circuit and the rms voltage across the resistance is 40 V.

A

10 V

B

20 V

C

30 V

D

40 V

Text Solution

Verified by Experts

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