A parellel circuit on the other hand, has two or more paths for current to flow through. The side adjacent to theta (θ) represents the true power. I.e. As shown in the above diagram, n resistors are connected in series so the same current passes through every resistor and the total resistance must be equal to the sum of all the resistors in the series.
