P-N Junction Diode and its applications: Practice Problem & Solution

When a PN junction diode is reverse biased :
Electrons and holes are attracted towards each other and move towards the depletion region
Electrons and holes move away from the junction depletion region
Height of the potential barrier decreases
No change in the current takes place

Solution Explained:

To solve this problem, we apply the core principles of P-N Junction Diode and its applications. Understanding the underlying formula is key to arriving at the correct answer below:

Factual Question: When a PN junction diode is reverse biased potential barrier of depletion increases. Thus Electrons and holes move away from the junction depletion region.
