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 average value of current for half cycle is

A

zero

B

`5/sqrt 2 A`

C

`10 A`

D

non of these

Text Solution

Verified by Experts

(a) `I = (V)/(R) = (100)/(20) sin100pit = 5sin100pit` therefore `I = (5int_(0)^(T) sin100pit "dt")/(int_(0)^(T) "dt") = 0`
