¶ Requirements
- Variable DC power supply
- 1kΩ resistor
- Zener diode
- Multimeter
¶ Schematic
¶ Usage
- Set up schematic onto a breaboard.
- Power on power supply at low voltage.
- Check the same voltage is on the multimeter.
- Raise slowly the voltage on power supply and check multimeter reading raising too at the same time.
- Stop when the multimeter doesn't update voltage along with the power supply.
- That's the maximum voltage of the zener diode.
