sherif, what you measured is voltage. current is measured in amps and milliamps.
normally (according to my physics and circuits classes) the ammeter should be placed between the esc and the motor in the circuit so that it's in series. this will tell you the current being drawn from the esc. my radioshack $19.99 digital multimeter, which can't handle more than 200mA, will only measure current when it's in parallel with the element. i guess it depends on what multimeter you have, i jsut found it odd that my multimeter behaved like that. so bascially, i would measure current the same way you would measure current, touch the leads on the two motor contacts. it's much easier this way than trying to wire my multimeter in series but it just goes against what i learned in class. heck, the ammeters in my labs required it to be wired in series. oh well, makes it easier for me. but now i need a multimeter with a wee bit higher range.
*Edit*
sorry for rambling on like that lol
