How does the width of the depletion region of a p-n junction vary, it the reverse bias applied to it decrease
Answers
Explanation:
If the reverse bias is applied to p-n junction then the width of the depletion region of a p-n junction will vary.
In reverse biasing, the positive terminal of the battery is connected to p type region and the negative terminal of the battery is connected to n type region.
There is no current flow in the reverse biasing until the diode breaks down.
When the negative terminal of the battery is connected to p type region then the holes in the p type region are pulled away from junction and when the positive of the terminal of the battery is connected to n type region then the electrons are pulled away from the junction.
This results in the leaving behind the charged ions which causes the width of depletion region to increase.

Explanation:
Width of the depletion region in a P-N junction decreases when it is forward biased whereas increases when it is reversed biased.
