A `100 Omega` resistor is connected to a 220 V, 50 Hz ac supply.
(a) What is the rms value of current in the circuit?
(b) What is the net power consumed over a full cycle?

A

`2.2 A , 484W`

B

`0.125A, 389W`

C

`4.2 A, 164W`

D

`2.7 A, 180W`

Text Solution

Verified by Experts

The correct Answer is:
A
Given, `V_(rms)=220V`
`R=100Omega implies I_(rms)=(V_(rms))/(R)=(220)/(100)=2.2A`
