hi, i was looking some internet pages about chopping on stepper motors, and i build a circuit with comparator + resistor senses + flip-flop and stuff. But i have a question: how can i know the current in the stepper coil motor? i means if i use the voltimeter in a coil and it's 1.2v (for example) with a 1.3ohm coil, then the current is: 0,92A, right? or is it an error do it so? I dont know if it's ok because the chopper frequency or something more, or not.

Thanx a lot if you can help me with this.

PD: sorry for my english.
