Reviews the operation of parallel RC circuit and specifically points out how to solve for branch currents and total impedance by using ohm's law. Reviews vector representations and show how approximate total current and phase angle are found by measuring the vectors. Introduces trigonometric functions used to solve for total impedance, total current, phase angle, and power factor. Concludes with a brief review of apparent and true power and their relationship to the power factor.
