A resistor and a capacitor are connected to an ac supply of 200 V, 50 Hz, in series. The current in the circuit is 2A. If the power consumed in the circuit is 100 W then the resistance in the circuit is

A

`10 0 Omega`

B

`25 Omega`

C

`sqrt (125 xx 71) Omega`

D

`400 Omega`

Text Solution

Verified by Experts

`FR = 100`
`R = (100)/( I ^(2)) = (100)/( (2) ^(2)) = 25 Omega`
