Reactance VS Impedance|Difference between Reactance and Impedance.
Introduction: Difference between Reactance and Impedance In the world of electrical circuits, reactance and impedance play vital roles. Reactance refers to the opposition encountered by inductors and capacitors when connected to AC.
In a Direct Current, or DC circuit, the opposition to current flow is called Resistance, but in an AC circuit, impedance is the result of both the circuits resistive (R), and reactive (X) components.
Impedance We now arrive at impedance. Impedance is a mixture of resistance and reactance, and is denoted by (Z). This can be visualized as a series combination of a resistor and either a capacitor or an inductor. Examples …
