- RMS value
- Zero
- Half of maximum value
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Concept:
A sinusoidal AC has equal positive and negative half cycles.
Step 1: During positive half cycle, current is positive.
Step 2: During negative half cycle, current is negative.
Step 3: Over one complete cycle, positive area and negative area cancel each other.
Step 4: Therefore, the average value over one complete cycle is: \[ 0 \] Hence: \[ \boxed{0} \]
Step 1: During positive half cycle, current is positive.
Step 2: During negative half cycle, current is negative.
Step 3: Over one complete cycle, positive area and negative area cancel each other.
Step 4: Therefore, the average value over one complete cycle is: \[ 0 \] Hence: \[ \boxed{0} \]
