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

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 an unbiased PN junction, immobile positive donor ions on the N-side and negative acceptor ions on the P-side form the depletion region. The electric field points from N to P, meaning the N-side is at a higher electrical potential.
