Thanks for the help gentlemen i really appreciate it. Just one more question. If the servo I am buying does not have a spec on current draw, could i just measure the resistance of the servo, and use Ohm's law? Is it applicable here or is the resistance constantly changing?
That will tell you the stall current of the motor so that is the absolute maximum it will take. In normal operation it will take much less, maybe 8 or 10 times less.
or is the resistance constantly changing?
The resistance is constant but the current through the inductor depends on the energy coupling between the magnetic field and the load you put it under.
