Question

An ac voltage is given as \(v = 14\sin(314t)\,\text{V\). The average and the effective value of the voltage (in V) over a cycle are respectively :}

• A. \(14\) and \(7\)
• B. \(10\) and \(14\)
• C. \(0\) and \(10\)
• D. \(10\) and \(0\)

Hint:

For any sinusoidal alternating voltage or current: \[ V_{\text{avg}}=0 \] (over a complete cycle) and \[ V_{\text{rms}}=\frac{V_0}{\sqrt2}. \] Always remember the factor \(\sqrt2\) while converting peak values into rms values.

Answer 1

The Correct Option is C
