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

where z1 is the impedance (in ohms) of pathway 1 and z2 is the impedance (in ohms) of pathway 2.
(a) The impedance of each pathway in a parallel circuit is found by adding the impedances of all components in the pathway. Use the table to find z1 and z2

(b) Find the impedance z.
