(I) For sinusoidal curve 
and average current for positive half cycle is 
.
(II) Let us find the average current (or rms current) for 
to 
. Then it will also be average current (or rms current) for half cycle, i.e., from 
to 
.
For 
to 
then 
and 
Full cycle average current is zero.
(III) For positive half cycle, average current
Full cycle average current is zero.
(IV) Average current for positive half cycle is 
. For full cycle, average current
and
