Common-Core Grade 9 - 9 Forward bias and reverse bias description
|
The P-side of the diode is attached to the positive terminal and N-side is fixed to the negative side of the battery.
When the junction is reverse biased that is when the p side is connected to the negative terminal, and the n side is connected to the positive terminal of the battery.
In forward biasing the applied potential difference causes a field which acts opposite to the potential barrier.
A forward bias has a substantial forward current
When the p-type is connected to the battery's negative terminal and the n-type is connected to the positive side, the P-N junction is reverse biased.
If reverse bias is increased, the current through PN junction will also increase
A reverse bias increases p-n diode depletion layer width, which offers resistance to the flow of charge carriers.
When the p-type and n-type side of a diode is connected to the +ve and −ve terminal of a battery.
Forward biasing means putting a voltage across a diode
The current in reverse bias is very small.
