Question

For a given AC source the average-emf during the positive half cycle. (A) depends on E0 (B) depends on shape of wave (C) both 1 and 2 (D) depends only on peak value of E0

Eav=(2E0/T)∫t/20 sin(ω t)dt=(2E0/π)

Q. For a given AC source the average-emf during the positive half cycle.

depends on $E_{0}$

depends on shape of wave

both 1 and 2

depends only on peak value of $E_{0}$

$E_{a v} = \frac{2 E _{0}}{T} \int_{0}^{t /2}$ sin $(ω t) d t = \frac{2 E _{0}}{π}$

depends on E0​

depends on shape of wave

both 1 and 2

depends only on peak value of E0​

Eav​=T2E0​​∫0t/2​ sin(ωt)dt=π2E0​​
