The formula to calculate the Zener Current (Iz) is:
\[ I_z = \frac{V_i - V_z}{R_z} \]
Zener Current is defined as the current passing through a zener diode when it is in operating mode.
Input Voltage is the voltage required at the input terminal of an electronic device to ensure the flow of current through it.
Zener Voltage is the threshold voltage at which a zener diode conducts current in reverse direction. It is determined by the doping concentration of the diode.
Zener Resistance is calculated when the zener diode is operating in the breakdown region, i.e., the region where it is conducting current in reverse direction.
Let's assume the following values:
Using the formula:
\[ I_z = \frac{21.21 - 10.6}{70.67} \approx 0.150134427621339 \]
The Zener Current is approximately 0.150134427621339 A.
