Question

what is rectification and explain half wave and full wave rectification

Answer 1

Rectification is the conversion of alternating current (AC) to direct current (DC). Ahalf-wave rectifier is a circuit that allows only one half-cycle of the AC voltagewaveform to be applied to the load, resulting in one non-alternating polarity across it.

Answer 2

If an alternating voltage is applied across a diode the current flow only in that part of the cycle when the diode is forward biased. This property is used to rectify alternating voltages and this process is known as rectification. the circuit used for this purpose is called rectifier.

In other words, the conversion of alternating current in which direction is periodically reversed, to direct current, which flows in only one direction is called rectification.

a half wave rectifier is a type of rectifier which converts the positive half cycle (positive current) of the input signal into pulsating DC (Direct Current) output signal. This process is known as half-wave rectification. Refer to diagram 1

a full Wave Rectifier is a circuit, which converts an ac voltage into a pulsating dc voltage using both half cycles of the applied ac voltage. This process is called full-wave rectification.Refer to diagram 2
