Hello. I finished my Electronics homework… but I’m not so 100% sure if I did it right. The problems that I have doubts about are number 5 and 6. Respectively a zener voltage regulator with fixed power supply and load, and a zener voltage regulated with fixed power supply and variable load. In both problems, I need to find the voltage and the current in each resistor. In problem number 5, I also need to find the power in each resistor and the zener. Anyways, this is pretty much what I did. I also simulated the circuit, just to compare if the voltages are the same. I realized that they are not equal, but are close from the simulation’s voltage.
