When Diode is Forward Biased?

By Mandeep Kumar|Updated : July 20th, 2022

When the voltage across a diode allows the natural flow of current then the diode is said to be in forward bias condition. On the other hand, a voltage across the diode in the opposite direction denotes reverse bias.

Answer: A diode is forward biased when the voltage across a diode permits the natural flow of current.

A diode allows the flow of current in one direction. Bias refers to the method of establishing a set of currents or voltages at different points of an electronic circuit for the proper functioning of the electronic component. When the voltage moves in the reverse direction then it is referred to as a condition of reverse bias. The voltage present in a diode during reverse bias condition does not develop any significant flow of current.

In forward bias, a positive voltage potential is connected to the P-type material and the negative voltage potential is connected to the N-type material across the diode. In reverse bias, a negative voltage potential is connected to the P-type material and a positive voltage potential is connected to the N-type material across the diode.

Summary:

When Diode is Forward Biased?

When the voltage potential is connected to the P-type and the negative voltage potential is connected to the N-type and the voltage across a diode allows the flow of current is known as forward bias condition.
