... Impedance . Electrical impedance, or simply impedance, describes a measure of opposition to a sinusoidal alternating current (AC). Electrical impedance extends the concept of resistance to AC circuits, describing not only the relative amplitudes of the voltage and current, but also the relative phases. ... Resistance is the real part of impedance; a device with a purely resistive impedance exhibits no phase shift between the voltage and current. ...
