Question:

The average value of a.c. over a full cycle in an ac circuit is: (Given $I_0$ = Peak current)

Options:

zero

${\frac{I_0}{\sqrt{2}}}$

${I_0}{\sqrt{2}}$

${\frac{I_0}{π}}$

Correct Answer:

zero

Explanation:

The correct answer is Option (1) → zero

Average value over full cycle because the current spread equal time in positive and negative directions.
