How it works

Zener Diode Calculation:

Here are the full calculations for this circuit using-

Input Parameters

Input Voltage (Vs): 12V

Series Resistor (Rs): 470 Ohm

Load Resistor (RL): 1000 Ohm

Zener Voltage (Vz): 5.6V

Total Source Current (Is)

Is = (Vs - Vz) / Rs

Is = (12V - 5.6V) / 470 Ohm

Is = 6.4V / 470 Ohm

Is ≈ 0.0136 A (or 13.6 mA) ≈ 14mA

What's inside

1× Battery
2× Resistor (470 Ω, 1 kΩ)
1× Diode
Measured with Voltmeter/Ammeter
