In a circuit, three wires form a junction. The current in one of the wires is either the sum of the currents and the other two wires or the difference between the currents of the other two wires.

Electric current is defined as the movement of charged particles (electrons or ions) through a current-carrying conductor, under the effect of potential difference induced between the ends of the conductor. It's measured in Ampere(A), which is the SI unit for current. Current in a circuit is measured using a device referred to as an ammeter.

When several conductors or semiconductors come into physical touch, the result is an electrical junction. Thermoelectricity junctions, metal-semiconductor junctions, and p-n junctions are a few different forms of electrical junctions.
