Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Concept:
The average value of a sinusoidal AC over one half cycle is:
\[
I_{\text{avg}}=\frac{2I_m}{\pi}
\]
Step 1: For sinusoidal current: \[ I_{\text{avg}}=\frac{2I_m}{\pi} \]
Step 2: Since: \[ \frac{2}{\pi}=0.637 \] \[ I_{\text{avg}}=0.637I_m \] Therefore: \[ \boxed{0.637I_m} \]
Step 1: For sinusoidal current: \[ I_{\text{avg}}=\frac{2I_m}{\pi} \]
Step 2: Since: \[ \frac{2}{\pi}=0.637 \] \[ I_{\text{avg}}=0.637I_m \] Therefore: \[ \boxed{0.637I_m} \]
