Vedclass · Answer

(A) The time period $T$ of the $AC$ source is given by $T = \frac{1}{f} = \frac{1}{60 \,Hz} \approx 0.01667 \,s = 16.67 \,ms$.The average value of an alternating voltage $V(t) = V_m \sin(\omega t)$ over one complete cycle (time interval $T$) is given by $V_{avg} = \frac{1}{T} \int_{0}^{T} V_m \sin(\omega t) \,dt$.Since the integral of a sine function over one complete period is zero,the average voltage over $16.67 \,ms$ must be zero.

An $AC$ source is rated $222 \,V, 60 \,Hz$. The average voltage is calculated in a time interval of $16.67 \,ms$. It
