Load
Place the 100 Ω resistor between +12 V and drain.
Build a basic IRF3205 circuit with labeled pins, component values and connection guidance.
Separate gate driver and load paths keep the connections clear.
Follow the component values and pin connections
Place the 100 Ω resistor between +12 V and drain.
Drive gate from 0 / 12 V through 100 Ω.
Connect source and driver return to the common ground.
