Design a 7.5-V zener regulator circuit using a 7.5-V zener specified at 12mA. The zener has an incremental resistance r(z) = 30 ohms and a knee current of 0.5mA. The regulator operates from a 10-V supply and has a 1.2k-ohm load.
1)What is the value of R you have chosen?
2)What is the regulator output voltage when the supply is 10% high?
3)Is 10% low?
4)What is the output voltage when both the supply is 10% high and the load is removed?
5)What is the smallest possible load resistor that can be used while the zener operates at a current no lower than the knee current while the supply is 10% low?
6)What is the load voltage in this case?
