CBSE · Class 12 · Physics · Semiconductor ElectronicsIn a p-n junction diode under reverse bias:
Step-by-Step Solution
In reverse bias, the negative terminal of the battery is connected to the p-side and the positive terminal to the n-side. This pulls majority charge carriers away from the junction, widening the depletion region and offering a very high resistance.
Detailed Options Breakdown
Option : The depletion region widens (Correct Answer)
Correct choice. Refer to the step-by-step verified solution guidelines above for details.
Option 1: The depletion region narrows
Incorrect choice. This distractor represents a common misunderstanding of the core principles of Semiconductor Electronics.
Option 2: Resistance becomes zero
Incorrect choice. This distractor represents a common misunderstanding of the core principles of Semiconductor Electronics.
Option 3: Current flows easily
Incorrect choice. This distractor represents a common misunderstanding of the core principles of Semiconductor Electronics.
