Effective Current

Find the effective value of the alternating current that changes according to the law :

I = I_o when 0 < t < T/8
I = 0 when T/8 < t < T/2
I = -I_o when T/2 < t < 5T/8
I = 0 when 5T/8 < t < T
I = I_o when T < t < 9T/8

etc.,

Total heat produced over a cycle with a resistance R
= Integral over 0 to T (I²Rdt)
= I₀²RT/4
Thus I_eff= I₀/2
