how to measure current on electric motor?
i have a small motor that runs off 6v DC. I am trying to figure out how to read the current of the motor so I can put an AC adapter on it. I have a multi-meter and I'm not getting any readings. I've been putting the multimeter on the + and - of the power cable going to the motor. what am i doing wrong?

ok i figured out i had to break the circuit and got it to work. new question tho. if i set the multimeter on DCA @ 20m I get a reading between .10 and .12. It fluctuates a bit. So being this is a 6V system what AC adapter would I be looking for? 6V and what current?
Thanks.
Thanks.

Actually any AC/DC adapter with an output of 6 volts and an amperage greater than the motor's draw. I would look for 6 volts and 300-600 milliamps output. The adapter only supplies as much current the motor needs (draws).
