write the reason that can make Zener voltage equal to 0 (more than 1 reason)
1)The foremost reason could be permanent damage to the zener diode causing it to act like a short circuit.
And also zener breakdown voltage is inversely proportional to its doping concentration.
2)So if doping is extremely high then we can make the zener voltage zero. ( but it is a hypothetical case)

Design a 7.5-V zener regulator circuit using a 7.5-V zener specified at 10 mA. The zener has an incremental resistance rz = 30 Ω and a knee current of 0.5 mA. The regulator operates from a 10-V supply and delivers a nominal current of 5 mA to the load. What is the value of R you have chosen? What is the regulator output voltage when the supply is 10% high? Is 10% low? What is the output voltage when both...

In the short-term Consumption can be greater than Income. Explain why the reason is more financial than economic.
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...
