Why is a zener diode used in reverse bias?
Answer : A Zener diode is used in reverse bias because that's how it operates to regulate voltage. Normally, diodes allow current to flow in only one direction (forward bias), but a Zener diode is designed ... that's when it can regulate voltage or protect circuits by limiting the voltage to a safe level....
