Electrical impedance or simply impedance is a measure of opposition to a sinusoidal electric current. The concept of electrical impedance generalizes Ohm's law to AC circuit analysis. Unlike electrical resistance, the impedance of an electric circuit can be a complex number. Oliver Heaviside coined the term impedance in July of 1886.

- Impedance (measured in Ohms) is the measure of the resistance to current that a circuit presents over a given voltage, or the ratio between the rms values of current and voltage. In DC circuits, impedance is the same as resistance. Impedance is a complex number, with resistance being the real part and reactance being the imaginary part. In general, the formula for impedance is With R being the resistance, j the imaginary unit (not i to avoid confusion with current), XL being the inductive reactance, and XC being the capacitive reactance.
