Vedclass · Answer

(B) The form factor is defined as the ratio of the root mean square $(RMS)$ value to the average value of the output voltage.Form factor $= \frac{V_{	ext{rms}}}{V_{	ext{avg}}}$For a half-wave rectifier,the $RMS$ value of the output voltage is $V_{	ext{rms}} = \frac{V_{	ext{max}}}{2}$.The average value of the output voltage is $V_{	ext{avg}} = \frac{V_{	ext{max}}}{\pi}$.Therefore,the form factor $= \frac{V_{	ext{max}} / 2}{V_{	ext{max}} / \pi} = \frac{\pi}{2} \approx 1.57$.
