Impedance, denoted Z, is an expression of the opposition that an electronic component, circuit, or system offers to alternating and/or direct electric current.Impedance is a vector (two-dimensional)quantity consisting of two independent scalar (one-dimensional) phenomena: resistance and reactance.
Difference Between Resistance and Impedance. When you say impedance in electricity, it is often used to described as the measure of the opposition to an alternating current (AC). It is basically resistance but the concept is extended to AC circuits. In AC circuits, amplitudes of both voltage and current, the phases, are shifting and relative. Impedance, in its simplest form, happens with Direct Current (DC); in that case, it is no different from resistance.
