Copper wire. Three different thicknesses of copper wire. The thickness of the wire affects the rate of the flow of electrons through the wire. The thicker the wire, the greater the current. Current is measured in amperes (A). From left: 5 A, 15 A and 30 A. The wires are insulated by rubber tubing (red).
