I have a circuit set up like so: All in series, induction coils with internal resistance 22 ohms, attached to a resistor of 40 ohms.(adsbygoogle = window.adsbygoogle || []).push({});

When AC current is induced in the coils at a certain rate, the voltage dropped across the resistor is .14 V AC. The current, which should be the same throughout the entire circuit, is .003 amps AC.

I am trying to find out how much voltage is induced in the coils (as if there had been no internal resistance, nor a resistor). The .14 V seems to be the "terminal" voltage, so I'm guessing that more than .14 V are induced in the coils.

Am I thinking about this correctly? How would I find the induced V? If anything needs clarification, then please ask.
