WebOhm's Law is a very basic law for calculating voltage drop: V drop = I·R. where: I: the current through the wire, measured in amperes. R: the resistance of the wires, measured in ohms. The resistance of the wires is often measured and given as length-specific resistance, normally in the unit of ohms per kilometer or ohms per 1000 feet. WebI worked retail for ~30 yrs, part time.
