How to Evaluate Zener Resistance?

Zener Resistance evaluator uses Zener Resistance = Zener Voltage/Zener Current to evaluate the Zener Resistance, The Zener Resistance is defined as the opposition offered to the current flowing through the Zener diode in the operating region. It is also known as Zener Impedance (Z_Z). Zener Resistance is denoted by R_z symbol.
