The potential difference across a circuit is represented by 40 + j25 volts, and the circuit consists of a coil with an inductance of 0.06H in series with a resistance of 20 Ohms. If the frequency is 80Hz find the complex number in rectangular form that represents the current in amperes.

I think that I am able to solve this problem, but I'm just not sure how to retrieve the voltage, is it as simple as converting the 40 + j25 into polar form? Which would make the voltage 47 Volts at an angle of 32? Is this correct?

I understand that the potential difference is the voltage, but i'm just not sure what to do with the complex number to begin with.

Thanks.
