Question

The rms value of current in a $50Hz$ AC circuit is $6A$. The average value of AC current over a cycle is

• A. $6\sqrt{2}$
• B. $\frac{3}{\pi \sqrt{2}}$
• C. Zero
• D. $\frac{6}{\pi \sqrt{2}}$

Answer 1

The correct option is C Zero

Average value of AC current over a cycle is zero as current is negative for same amount of time that it is positive.
