Zener Regulators: Series Resistor, Zener and Load Currents, Power vs Rating & the Load Window

Lesson 3 of 816 minLab

This lesson is part of the course

In this lesson

You compute the series-resistor current at the lowest and highest input, split it into Zener and load current for six loads, compare the Zener power with a fictional rating and find the load window that stays in regulation and within rating.
