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. Often confusing and contradictory, electrical voltage drop symptoms vary according to the circuit’s job and the severity of the voltage drop. 1. Inoperative electrical parts 2. Sluggish, lazy electrical devices 3. Erratic, intermittent devices 4. Devices that work sluggishly or erratically during periods of high electrical loads 5. … See more Whenever an electrical problem gives you fits, take a deep breath and think of the basic electrical building block: the series circuit. No matter how complicated a system is, you can always simplify it to smaller series of … See more Excessive resistance on an electrical circuit can cause a restriction in current flow.
