$\mathrm{i}=50\sin 100\mathrm{t}\mathrm{A}$
∴ The peak value of current, I = 50 A
Average current over half cycle = Average value of sinusoidal current:
$\Rightarrow \frac{2\mathrm{I}}{\mathrm{\pi }}=\frac{2\times 50}{\mathrm{\pi }}\mathrm{A}$
∴ Average current over half cycle $=\frac{100}{\mathrm{\pi }}\mathrm{A}$
Average current over complete cycle $=0\mathrm{A}$
