Ctri Question 3 (20 Marks) Lab 1-Zener Circuits and Applications Theory: Zener diode is designed to operate in reverse conduction. Zener breakdown occurs at a precisely defined voltage, allowing the diode to be used as a voltage reference or clipper. While Zener diodes are usually operated in reverse conduction, they may also be operated in cutoff and forward conduction. There are two different effects that are used in "Zener diodes". The only practical difference is that the two types have...
