Please help. I want to run a radio control model servo from a computer usb port at 3.3v (so it runs slower) Testing the current draw with a multimeter from 3.24volts, it showed 0.06A so using ohm's law the servo load resistance should be 54 ohms right? 3.24 รท 0.06 = 54 When I test the resistance of the servo (by measuring the resistance across the positive and negative terminals of the motor) with the multimeter set to resistance 200 the reading is 08.0 which is 8 ohms right? Not 54 ohms. Please explain what I am doing wrong.
