This electronics video tutorial provides a basic introduction into power zener diodes and it explains how to use them as voltage regulators. It provides a full circuit analysis on the relationship of the zener voltage and the amount of electric current flowing through the diode. It also shows how the zener diode can maintain a stable output voltage when the voltage of the power source varies. In addition, it explains how to load resistance affects the performance of the zener diode. Finally, this video explains how calculate the value of the current limiting resistor to yield maximum efficient by the external circuit.
