FAQs

Question: What is the main function of a Zener diode?
Answer: A Zener diode is primarily used for voltage regulation by allowing current to flow in the reverse direction when a specific voltage is reached.

Question: How do you determine if a diode is in forward or reverse bias?
Answer: A diode is in forward bias when the anode is at a higher potential than the cathode, allowing current to flow; it is in reverse bias when the cathode is at a higher potential, preventing current flow.
