    Thank you very much sir, but my question is what is the value of starting resistor, or should I just connect diode across it as shown in your diagram?

      This circut work at 12v so you dont need any starting resistor. i have used that diode just as a reverse polarity protection 😆😁😁

    Hello Sir... me again... 🤭
    The mosfet IRF44n spec is 55V-49A. And I think your circuit have constant voltage (CV) features, wich set by 20K variable resistor.
    1. How to drive more current at your circuit? (Of course we need good cooling system)
    2. How to control current with variable resistor so we have constant current?

    • @kdcreativity6201
