EXPERIMENT 2

Full-Wave Rectification Using Bridge Rectifier

Objectives: To recognize a full-wave rectified sinusoidal voltage using bridge.

Equipments and Components used: Power supply (220V)

Step down transformer (220-12)

Four diode (D1-1N4001)

Resistance (10kΩ)

Comments:

There is error of 0.86, which might be the result of cumulative errors built up from

approximation used in ideal model.

A full-wave rectifier converts the whole of the input waveform to one of constant polarity

(positive or negative) at its output.
