To get them to move in the same direction they need a push. The technical term for this push is electromotive force, abbreviated EMF, or sometimes simply E. But you know it more commonly as voltage.

1. Voltage is the force that causes electrical current to flow.
2. Current, or amperage, refers to the rate electricity is flowing.
3. Resistance is a material’s tendency to resist the flow of the current.
4. Conductivity refers […]
