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

The increase in the width of the depletion region in a p-n junction diode is due to : (2020)
Reverse bias only
Both forward bias and reverse bias
Increase in forward current
Forward bias only

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:

In reverse bias, the applied electric field aligns with the built-in electric field of the junction, pulling majority carriers away from the junction. This widens the depletion region.[cite: 1]
