Average Half Cycle Value = 2V / pi
= 2 * 40 / 3.14
= 25.48
= 2 * 40 / 3.14
= 25.48

Your answer is wrong
Correct answer 14.14
Peak value = v*ROOT2
V=(PV/ROOT 2)/2
Correct answer 14.14
Peak value = v*ROOT2
V=(PV/ROOT 2)/2

Vavg = Vp x 0.637
= 40 x 0.637
= 25.48 V
= 40 x 0.637
= 25.48 V

@siba.
25.48 not wrong. Becuse always average value taken for half cycle. For complete cycle its value zero.

Vavg = (2*Vm)/pi.
= (2*40)/3.14.
= 25.48.
= (2*40)/3.14.
= 25.48.

Integrate 40 sin t = 0, pi.
We get 2*40 = 80 then divide by pi.
We get 25.48 = ans.
We get 2*40 = 80 then divide by pi.
We get 25.48 = ans.

I am not getting your answer clearly @Pradeep Jaiswal.
Please explain me in detail.

For Sine Half wave value should be= Vp/π
For Sine Full Wave its value becomes= 2 Vp/π.
For Sine Full Wave its value becomes= 2 Vp/π.
