An alternating current having peak value...

An alternating current having peak value 141 A is used to heat a metal wire. To produce the same rate of heating effect, another constant current IA is used. What is the value of I?

Text Solution

Verified by Experts

`I_(rms)=I_0/sqrt2=(141A)/sqrt2=100A`
IF a steady dc current I produces the same rate of heating , then `I=I_(rms)=100A`.
