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

Text Solution

Verified by Experts

a. `V_(rms) = (V_(rms) )/(sqrt2) = (300)/(sqrt2) = 212.1 V`
b. `I_(rms) = (I_(rms) )/(sqrt2) therefore I_(rms) = sqrt(2) I_(rms) = sqrt(2) xx 10 = 14.14 A`
