Impedance
Hello,
How do i calculate the impedance of an electrical circuit when i have a resistor, inductor and capacitor.
Thanks

It depends on the configuration of the circuit, that is are the components in series, parallel, quantity etc.
The general impedance formula for a resistor and inductor or capacitor in series is
,
where Z is the impedance, X is the reactance of capacitor/inductor, and R is the value of the resistor.

To calculate the impedance, you need to know all kinds of reactance for the RLC circuits, the one for the resistor, capacitor and inductor. It is:
Z is the impedance, R the reactance of the resistor and X the difference of the reactance for both inductor and cpacitor, so X = XL - XC. This sketch may help you to understand the mathematical background:
