Currents and Phase relation in AC circuit with L, R, and C.

[risendemon]

Homework Statement

The voltmeter in the circuit sketched in the link below reads 100 volts. What currents would ammeters indicate for I1, I2, and I3? What is the phase relation between the applied voltage and I3?

Homework Equations

This is what I need help with, actually...

The Attempt at a Solution

So, I don't really want help in solving the problem, I just need a push in the right direction. Mostly something along the lines of what equations I need, or how to start going about looking at this problem. Anything at all will help me immensely

thanks a bunch!

Here's a hint: The voltage source produces a waveform of 100 cos(120 pi t) volts.

need to convert all impedances and source into phasors (complex number) first and do the usual circuit analysis with complex numbers.

eg: $$Z_L = j \omega L$$ where $$j=\sqrt{-1}$$ and $$\omega$$ is angular frequency.
