SERIES - PARALLEL CIRCUIT COMPARISON In a series circuit: • The total resistance always increases as more elements are added to the circuit. As a result, the total amount of current flowing always decreases. • To maintain the same current as more elements are added, greater and greater voltage will be needed from the power source. • If the wire size is sufficient (or can be ignored) for a single element in the circuit, then wire size will generally be sufficient if more elements are added. In a parallel circuit: • The total resistance always decreases as more branches are added to the circuit. As a result, the total amount of current flowing always increases. • To maintain the same current through each branch, as more branches are added, the power source and wire must be capable of supplying all of the additional current. • As more branches are added, the resistance of the wiring becomes increasingly important and cannot be ignored.
