Question

If the voltage of a source in an AC circuit is represented by the equation, $E=220\sqrt{2}\sin \left(314t\right)$. Calculate the average voltage of the signal for full cycle.

• A. $220\text{V}$
• B. $220\sqrt{2}\text{V}$
• C. $314\text{V}$
• D. $0\text{V}$

Answer 1

The correct option is D $0\text{V}$

$E=220\sqrt{2}\sin \left(314t\right)$ is a sinusoidal voltage signal. For a sinusoidal voltage signal, average voltage in a full cycle is zero.
