Calculates the total resistance of a circuit when multiple resistors are used.
Series circuits are circuits where the resistors are wired end to end so that the current only has one path to flow.

Parallel circuits are wired in a manner that allows the current to flow through multiple paths.

Combination circuits are circuits that contain resistors wired in both series and parallel. To calculate the total resistance of a combination circuit, you must first find the total resistance of all resistors wired in series. Next find the total resistance of the resistors wired in parallel. The total resistance of a combination circuit can be found by adding these totals together.
