[397] How To Calculate Zener Regulator Circuit / Zener Series Resistor Calculation

in this video i discussed How To Calculate Zener Regulator Circuit / Zener Series Resistor Calculation. i used 400 v dc rail and calculated zener resistor to get 24 volt 10 milli ampere current. i calculated the power disspation / power rating of the zener resistor this resistance will limit the current and it will drop the remaining supply voltage across itself
