I know one can use a LM317 to cut 12 volts dc to 1.5 volts but can one use resistors? I have a wall clock that runs a small motor to wind spring and it powered by a c battery you can run on more voltage without out damage to any thing as it only run for 1 second every 2 minutes. I tried a 30 ohm resistor but it still must be to much voltage as when it winds up the spring it it goes to far causing it not to release the switch when unwound. Do these small brush type dc motors draw a constant load from startup thru full speed running? can't imagine these motors draw many amps running off a c battery. I was also wondering when you use a resistor to cut voltage down do you also lose amps?
