Question

Draw a neat and labelled circuit diagram for a full wave rectifier.

Hint:

Think of the two diodes working in shifts. For the positive half of the AC cycle, D1 works. For the negative half, D2 works. The center-tap ensures they both push the current in the same direction through the load resistor.

Answer 1

A full wave rectifier converts both halves of an AC input signal into a pulsating DC output. A common circuit uses a center-tapped transformer and two diodes.
Components:
AC Source: Provides the input alternating voltage.
Center-tapped Transformer: Steps down the voltage and provides two AC signals that are 180° out of phase.
Diodes (D1, D2): Act as one-way gates, each allowing current to flow during one half-cycle of the input.
Load Resistor (RL): The output voltage is developed across this resistor.
