Manufacturing is a highly technical field that requires maintenance, electronic personnel, and engineers to have specific knowledge of ohms law when working on the various machinery. No matter what type of machinery is being used in you facility the knowledge of ohms law is necessary. Ohms law is the relationship between voltage, current and resistance in electrical circuits.
One should think of voltage as the pressure of electrons. Voltage is represented in Ohms law with the letter E. Voltage is represented on a volt meter in units of volts. Resistance is the lack of flow of electronics. Resistance is represented in Ohms law as the letter R. Resistance is represented on a volt meter in units of ohms. Current is the flow of electrons in a circuit. Current is represented in Ohms law with the letter I. Current is represented on a volt meter in units of amps.
