Question

The output current versus time curve of a rectifier is shown in the figure. The average value of the output-current is________ . 

(A) 0 

(B) (I₀ / 2) 

(C) (2I₀ / π) 

(D) I₀

Answer 1

The correct option is  (C) (2I₀ / π).

Explanation:

From the wavefrom, it is clear that is is full wave rectifies. And average

value of current is I_avg = {(2I_max) / π}

From wave from,     I_max = I₀ hence

I_avg = (2I₀ / π)
