From the following diode circuit. Which diode in forward biased condition:
The Correct Option is A
Solution and Explanation
A diode is considered to be in a forward-biased state when the p-type semiconductor of a p-n junction has a positive potential relative to the n-type semiconductor of the same junction.
So, the correct option is (A).

P-n Junction
A P-N junction is an interface or a boundary between two semiconductor material types, namely the p-type and the n-type, inside a semiconductor.
Biasing conditions for the p-n Junction Diode:
in p-n junction diode two operating regions are there:
- P-type
- N-type
There are three biasing conditions for p-n junction diode are as follows:
- Zero bias: When there is no external voltage applied to the p-n junction diode.
- Forward bias: P-type is connected to positive terminal of the voltage potential while n-type is connected to the negative terminal.
- Reverse bias: P-type is connected to negative terminal of the voltage potential while n-type is connected to the positive terminal.
