(a) The peak voltage of an ac supply is 300V. What is the rms voltage ?
The rms value of current in an circuit is 10V. What is the peak current ?

Text Solution

Verified by Experts

(a) `V_(rms ) = ( V_(m))/( sqrt(2))`
`= ( 300)/( 1.414)`
212.2 Volt
(b) (b) `I_(rms) = (I_(m))/(sqrt(2))`
`:. I_(m) = sqrt( 2) I_(rms)`
`= ( 1.414) ( 10)`
`:. I_(m) = 14.14A`
