An Ac source of volatage V=100 sin `100pit` is connected to a resistor of ressistance 20` Omega`The rsm value of current through resistor is

A

`10 A`

B

`10/sqrt 2 A `

C

`5/sqrt 2 A`

D

non of these

Text Solution

Verified by Experts

(c) `I_(0) = (V_(0))/(R) = (100)/(20) = 5 A` therefore `I_(rms) = (I_(0))/(sqrt 2) = (5)/(sqrt 2) A`
