Description : Which of the following is used for regulated electric supply? (1) Zener diode (2) Junction diode (3) Gun diode (4) Tunnel diode
Last Answer : (1) Zener diode Explanation: The Zener diode is like a generalpurpose signal diode. When based in the forward direction it behaves just like a normal signal diode, but when a reverse voltage ... property. Many diodes described as "Zener" diodes rely instead on avalanche breakdown as the mechanism.
