The opposition to current in an electrical circuit is called its impedance. The impedance z in a parallel circuit with two pathways satisfies the equation 1 where z, is the impedance (in ohms) of pathway 1 and z, is the impedance of pathway 2. The impedance of each pathway in a parallel circuit is found by adding the impedances of all components in the pathway (see table).
