Experiment #3 Zener Circuit

For R=100 ohms and RL=100 ohms, Vs=12V

What is the value of Vz?: 4.98V

Vary Vs from 10V to 15V
What is the value of Vz?: 4.74V - 5.06V

Explain what is happening here: At all stages of voltage, Vz stays at around 5V because the Zener is regulating the voltage to a maximum of 5.1V

What could this be used for?: As i stated above this circuit would be used as a voltage regulator.

Reverse the polarity of the Zener Diode
What is the value of Vz? Make a short comment why: .863V, this has happened because the Zener in reverse bias becomes like a regular foward bias diode.
