    how to measure the current consumption by dc motor

    in this circuit

    without DMM the motor is running fine.


    with DMM the motor is not running.



    the scope here is to measure the motor current through DMM.

    i tried 6 and half also. cant get result.

    anyone please help me out in this regards.

    any idea about measuring using arduino uno?

    Re: how to measure the current consumption by dc motor

    I am surprised. Most DMMs use a current shunt of a low value.

    Just for fun, try this experiment; use a 1 Ohm resistor in place of the DMM and measure the voltage across the resistor.

    The fuse in the DMM current circuit is burnt out.
