The impedance {in Ohms} is dened as the opposition to current in an electrical circuit (note that the impedance is a complex value]; The impedance 5 in a parallel circuit with two pathways satises the equation = + . {1) where :1 and :2 are the impedance in paths 1 and 2, respectively. The impedance of each pathway in a parallel circuit is found by adding the impedances of all components in the pathway. in correspondence with the table below: Table I : Impedance a} Let A = 115 = . IC' = 2. and D = 2. For the parallel circuit shown below in Figure I nd the impedances :1 and 33 in cartesian form. DR Figure 1: Parallel circuit
