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/z = 1/z1 + 1/z2, where z1 is the impedance (in ohms) of pathway 1, and z2 is the impedance (in ohms) of pathway 2. Use the table to determine the impedance of each parallel circuit. (Hint: You can find the impedance of each pathway in a parallel circuit by adding the impedances of all components in the pathway.)

Was there a diagram with a circuit?
When it says "Use the table to determine the impedance of each parallel circuit" There has to be a circuit or at least a table, to look at in order to answer this question.
