Question: In semiconductor physics, what happens to the resistance of a diode when it is forward-biased?

Options:

  1. Resistance increases
  2. Resistance decreases
  3. Resistance remains constant
  4. Resistance becomes infinite

Correct Answer: Resistance decreases

Solution: 

When a diode is forward-biased, its resistance decreases, allowing current to flow easily.

Questions & Step-by-Step Solutions

In semiconductor physics, what happens to the resistance of a diode when it is forward-biased?
  • Forward Biasing of Diodes – In forward bias, the positive terminal of the voltage source is connected to the anode and the negative to the cathode, reducing the barrier potential and allowing current to flow.
  • Resistance in Diodes – The resistance of a diode decreases significantly when it is forward-biased, which is a key characteristic of its operation.
