Expressed in rectangular form the inductors impedance has a positive imaginary term and the capacitor has a negative imaginary term. When these two contrary impedances are added in series they tend to cancel each other out. Series R L And C Reactance And Impedance R L And C Factors Of Making Noise Problems Complex Murata 1 C Manhattan Press H K Ltd Series Combination Of Again several conclusions can be drawn from this formula. Capacitor and inductor in series impedance . Capacitor and inductor oppose current in ac circuit because of inertia of electron motion which is called capacitive and inductive reactance respectfully. Reactance and resistance combine to impedance the overall opposition to ac current. The reactance of an ideal inductor and therefore its impedance is positive for all frequency and inductance values. The resistance of an ide...
