Question

If a current through an AC circuit is, $i=2\sqrt{2}\sin \left(314t\right)$. What is the average current for the full cycle through the circuit ?

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

Answer 1

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

Given, $i=2\sqrt{2}\sin \left(314t\right)$ is a sinusoidal current signal.

For a sinusoidal current signal, the average current through the circuit in the full cycle is zero.

Hence, $\left(D\right)$ is the correct answer.
