ACTIVITY 1
Go through the following explanation on half wave rectification and answer the questions at the Evaluation section.
Half wave rectification
In this case, the first half cycle of a sinusoidal waveform is positive and the inclusion of a reverse biased diode makes the current not to flow to the negative side of the wave. The current therefore, conducts on every half cycle hence a half wave rectification is achieved. The voltage is d.c. and always positive in value, though it is not steady and needs to be smoothed by placing a large capacitor in parallel to the load as shown.
ACTIVITY 2
