An impedance of the circuit is the total effective resistance or the opposition measure to the passage of current in an AC voltage source supply. It's unit is ohms and is given V = IZ. Resistance in the form of ohm's law, reamins constant in DC or AC circuits and is different in capacitor and an inductor. The Capacitor in DC circuit, as well as in an inductor is an open circuit,while in AC voltage source, the capacitive resistance is called reactance or Xc, on the other hand, inductive resistance is equal to the reactance or XL.
