Diode Definition?

A diode is a two terminal electronics device which is made by semiconductor material.

Diode Symbol

The arrow show the direction of convectional current Flow in forward direction.

IDEAL DIODE

The ideal diode is said ideal diode when the current follow in only one direction these direction is forward direction and it fully block the current follow in reverses direction.

MAJORITY CARRIER AND MINORITY CARRIER

In N-type semiconductor the electron are majority carrier and holes are minority carrier because the N-type is made by adding pentavalant impurity.

WORKING OF DIODE

The diode has two regions:- 1. Forward region 2. Reverse region

FORWARD BIAS

forward bias when the +ve terminal of the battery is connected to the anode terminal and the –ve terminal of battery is connected to the cathode terminal.

REVERSE BIAS

It is Reverse bias the reverse connection for forward bias
