What is RMS valur if ac? Definition pls in easy words i n not understanding it

Dear Student
We use the concept of rms current to know what equivalent DC current value would have to be used to provide the same level of power dissipation as is done by the alternating current.
That is, RMS value of current is that value of alternating current which would yield the same power dissipation in the circuit as done by steady current.
