Concept:

The average value of sinusoidal waveform over one complete cycle is zero as two halves cancel each other, so the average value is taken over half a cycle.

 

Therefore, the average value of a sinusoidal wave is 0.637 times the peak value.

Calculation:

Given,

Vavg = 12.74 V

= 19.57 V

∵ We are asked to find the peak to peak voltage.

∴ Vp-p = 2 × 19.57 ≈ 40 V
