Rectification

Full-wave

A process of converting a.c. to d.c. by a rectifier.

Reverse bias

Forward bias

Conduct current

does not conduct current

Low resistance

high resistance

type of rectifier

thermionic diode valve

selenium rectifier

semiconductor rectifier

supply larger amount currents

can withstand higher potential differences

sizes are smaller than metal rectifiers

Half-wave

first half-cycle

potential difference across resistor i created with the same value as applied potential difference

in forward direction of the rectifier

second-half cycle

current is in reverse biases direction

As the resistance in rectifier is very hgh

no current flow

potential difference across resistor is zero

produced when a rectifier is connected in series with an a.c. input and d.c. load such as resistor
