When currents in wires run parallel, the wires attract due to the magnetic fields from the currents and the Lorentz force. The currents can also be run anti-parallel, making the wires repel. Place the ...

Learn how to calculate electric current and potential in two connected wires! This guide walks you through the physics behind series and parallel circuits, helping you understand voltage drops and ...

The simplest complete circuit is a piece of wire from one end of a battery to the other. An electric current can flow in the wire from one end of the battery to the other, but nothing useful happens.
