    i need to know wat the current flow is if an inductor of 500mH is connected in parallel with a 1k resistor across a 110v, 60Hz source whats the current flow

    Hi,

    Solve for the impedance of the inductor, and treat it as a resistor in parallel with the fixed resistor. The values will be RMS volts and amps.

    This is certainly the most straight forward method of answering this question. From one of the above links from JoeJester, the inductive reactance XL is given by:

    XL = 2*pi*f*L

    All of this information is given in you original question.

    Knowing this and applying simple circuit analysis will yield the answer.

    If you post up your attempts it will be easier to point you in the right direction.
