The average half-cycle value of a sine wave with a \( 40 V \) peak is

1. \( 25.48 V \)
2. \( 6.37 V \)
3. \( 14.14 V \)
4. \( 50.96 V \)

Correct answer: \( 25.48 V \)

Solution

The average value over one half-cycle of a sine wave is \(\frac{2V_m}{\pi}\). With a peak value of 40 V, this gives \(\frac{2\times 40}{\pi} \approx 25.48\) V. That matches the correct option.
