## Homework Statement

A series RLC circuit is connected across a 6.70 kHz source. The 1.50 H inductor and the 1.35×10

^{3}kohm resistor are fixed whereas the capacitor is variable. At what capacitance will the current in the resistor be a maximum?

## Homework Equations

No idea..

## The Attempt at a Solution

I can't find any equations that will let me solve for capacitance in this situation. I know that current is maximum (resistance minimum) at resonance when Xl=Xc, and phi=0.

edit: nevermind, didn't think to just use Xl=Xc to solve for C...
