Voltage Divider Cooling. Needing heat help.


Thread Starter


I made a voltage divider to power a stepper motor. It requires 9V and I am using a 12V wall plug.

If you have used one before, have your experiences shown that your resistors get pretty hot to the touch?
We do not know enough bout the voltage divider.
No data on the motor.
Think about the power going into the motor. The power in the resistors is 33% of that. See how large the motor is and how small the resistor are. Yes they will get hot.
