22.6 RCL Series Circuits

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.
