mm ;..

(I r.m.s) and (I eff=i effective)are both of them same? how do we get value of both of them in C-R circuit??if we are given values of: frequency,C,R ,a.c voltage applied..

?

The effective current and rms current are basically the same. In a CR series circuit its value is

Irms =  I0/√2 = E0 / (2(R2 + (1/C2w2) ))

where E0 = peak voltage

R = resistance

C = capacitance

w = angular frequency
