Impedance
The opposition to power flow
in an AC circuit. Also, any device that introduces such opposition
in the form of resistance, reactance, or both. The impedance of a
circuit or device is measured as the ratio of voltage to current,
where a sinusoidal voltage and current of the same frequency are used
for the measurement; it is measured in ohms.
