how are zener diodes different from rectifier diodes? also mention the application of both
Answers
Answer:
Diode is the simplest semiconductor device and it consists of two semiconductor layers (one P-type and one N-type), connected to each other. Therefore, the diode is a PN junction. A diode has two terminals known as the anode (the P-type layer) and the cathode (the N-type layer).

A diode has two terminals known as the anode (the P-type layer) and the cathode (the N-type layer).Diode allows current to flow through it, only in one direction that is anode to cathode. This direction of current is marked on its symbol with an arrow head. Since the diode restricts the current to only one direction, it can be used as a rectifier. The full-bridge rectifier circuit, which is made of four diodes can rectify an alternative current (AC) to direct current (DC).

As mentioned in the previous paragraph, a normal diode will conduct a large reverse current and becomes permanently damaged when a large reverse voltage is applied. Zener diode will also conduct a large reverse current, but the device will not be damaged. This is achieved by changing the way of doping the PN junction and this reverse voltage is called the 'Zener voltage'.

Answer:
1. Rectifier diodes are used mainly for only allowing current/voltage to flow in one direction.
2. Zener diodes work a little differently, they conduct in reverse and can then recover unlike rectifier diodes.
