Introduction
The purpose of the experiment is that of examining a half and full wave rectifier circuit by recording and comparing the results of each circuit:
·Without a smoothing capacitor
·With a smoothing capacitor
To record the results on the ripple voltage by :
·Using different values of smoothing capacitors
·Varying the load current conditions
Theory Of Half Wave Rectifier Circuit
The half wave circuit is so called because current flows through the diode only for …

…discharge period B - C and charge period C - D is much less than that of the half wave circuit. Therefore the drop in voltage is less hence the ripple is reduced. It is easier to smooth the output of a full wave rectifier circuit than that of a half wave.
