Rectifiers

Diode 

•  allows current to flow in one direction
•  allows current to flow in two directions
• is a resistor

Diode is used as a half wave rectifier.

• It rectifies only one half of the input AC signal
• It rectifies both the  halves of the input AC signal

Diode is used as a full wave rectifier.

• It rectifies only one half of the input AC signal
• It rectifies both the  halves of the input AC signal
