Resistor gets really hot? Answered
I'm trying to build a simple circuit.
6V ---> potentiometer ---> Small DC Motor (dont know the specs)
First the potentiometer was getting hot a some smoke came out of it (its still working anyway). I thought this was happening because with 0 resistance on the potentiometer alot of current was flowing by. I added some resistors (not knowing exactly what value to add, i tried a few).
First 2k Ohms, motor didnt spin, 1k same thing, 800, 100, and finally around 5ohms. Now the motor spins and seems to be hanging on a bit better. However the 5ohm resistor is getting hot really fast....
What should I do to avoid draining the battery so fast, and keep the motor running for as long as possible (without burning resistors or the dc motor itself)
