How to Calculate Zener Current?
Zener Current calculator uses Zener Current = (Input Voltage-Zener Voltage)/Zener Resistance to calculate the Zener Current, Zener current consists of a current limiting resistor connected in series with the input voltage with the Zener diode connected in parallel with the load resistor in this reverse biased condition. The stabilized output voltage is always selected to be the same as the breakdown voltage of the diode. Zener Current is denoted by I_{z} symbol.
How to calculate Zener Current using this online calculator? To use this online calculator for Zener Current, enter Input Voltage (V_{i}), Zener Voltage (V_{z}) & Zener Resistance (R_{z}) and hit the calculate button. Here is how the Zener Current calculation can be explained with given input values -> 150134.4 = (21.21-10.6)/70.67.
