The current I through this RCL series circuit is related to the voltage V by
V = I Z
where Z is the total impedance of the circuit. As with XC and XL, the impedance Z will depend upon the frequency of the AC voltage. The total impedance Z is given by
Remember, of course, that the reactances XL and XC depend upon the frequency.
