Q: What is the primary function of a diode?

To allow current flow in one direction and block it in the other. — Diodes are designed to conduct current in one direction (forward bias) and block it in the opposite direction (reverse bias).

Q: In which bias condition does a diode conduct current?

Forward bias — Forward bias allows current to flow. Reverse bias generally blocks current (except for a very small leakage current).

Q: What part of a diode represents the positive terminal?

Anode — The anode is the positive terminal. Current flows from the anode to the cathode in forward bias.

Q: What is the purpose of the 'breakdown voltage' in a diode?

The reverse voltage at which the diode fails and conducts heavily. — If a reverse voltage exceeds the breakdown voltage, the diode will experience a catastrophic failure and conduct.

Q: What type of semiconductor material is typically used to create a diode?

Semiconductor — Diodes are made from semiconductor materials like silicon (Si) or germanium (Ge) due to their unique properties.
