Correct Answer - Option 1 : 1.11
The ratio of RMS value (RV) to the average value (AV) is known as the form factor.
\(Form\;factor = \dfrac{{RV}}{{AV}}\)
For a pure sinusoidal waveform, the average or mean value will always be equal to 0.637 Vmax
The RMS Value of AC signal is given by \(\dfrac{V_{max}}{√2}\)
\(Form factor=\dfrac{\dfrac{V_{max}}{√2}}{0.637V_{max}}\)
= 1.11
- For Square wave with zero DC value: 1
- For a Triangular wave with zero DC value: \(\frac{2}{\sqrt3}\)
- For a Full wave rectified sine wave: 1.11
