- Diode: A diode is a two-terminal electronic component that conducts current primarily in one direction; it has low resistance in one direction, and high resistance in the other.
There are two
- Forward Biasing:
- The forward bias means the positive region is connected to the p-terminal of the supply and the negative region is connected to the n-terminal of the supply.
- In forward biasing the external voltage is applied across the PN-junction diode.
- Reverse Biasing:
- In reversed bias, the negative region is connected to the positive terminal of the battery, and the positive region is connected to the negative terminal.
- It creates a high resistive path in which no current flows through the circuit.
EXPLANATION:
- In reverse-biased the negative potential is applied to the P- region and a positive potential is applied to N - region.
- Which attracts the electrons on the N- side towards the positive potential and the holes in the P - region is attracted to the negative potential applied on the P - region, which means the reverse current is produced due to the movement of both electrons and holes respectively.
- Hence, option 4 is the answer
