Vedclass · Answer

(A) The given alternating voltage is $E = 20 \sin 300t$.The average value of a sinusoidal alternating voltage over one complete cycle is defined as the integral of the voltage over the time period $T$ divided by the time period $T$.Mathematically,$E_{avg} = \frac{1}{T} \int_{0}^{T} E_0 \sin(\omega t) dt$.Since the sine function is symmetric about the time axis,the area under the positive half-cycle is equal to the area under the negative half-cycle.Therefore,the positive and negative values cancel each other out,resulting in an average value of $0$ over one complete cycle.

An alternating voltage is represented as $E = 20 \sin 300t$. The average value of voltage over one cycle will be ....... $V$.
