The total current in a parallel circuit is equal to the sum of the currents through all the circuit branches.

Currents in a parallel circuit add up. The current from the source splits into separate branch currents, and the total entering the parallel network equals the sum of those branch currents. This follows Kirchhoff’s current law: what goes into a junction must come out, so the source current is the sum of the currents in each branch. Each branch has the same supply voltage, but its current depends on that branch’s impedance, so adding all branch currents gives the total current drawn. For example, if one branch carries 2 A and another carries 3 A, the source provides 5 A. The idea of a series current describes the constant current through a single path, not the sum of multiple branches; total resistance is a separate concept that affects current, not the amount of current itself; and total current is the actual current supplied, which in a parallel circuit is the sum of all branch currents.
