Answer / raghu

imagine a dc current flowing in a resistive ckt.. it
produces (i^2)*R heat.. now imagine ac current in the same
ckt.. find out the power dissipated in the network by
integrating the sum of the squares of the instantaneous
values of the current under root.. and equate it to the
power dissipated by dc current.. the value obtained is rms
value..
