# What is ohm's law?Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points.

## The practical significance of Ohm's Law practical Ohm's law is the measurement of electrical current-voltage resistance as it required in electrical or mechanical Industries it is imperative to have a method by which we can measure all of these quantities at is electrical quantities on parameter.Resistance current and voltage EMF can all be determined by the base of the formula which is needed by industrial training for designing the circuit it is also compulsory.Ohm's law is mainly used to find out all the desired amount of resistance voltage or current level to make sure that we are able to design a proper electrical circuit systemIt is applicable to decide the rating of the home and electrical appliances by using the Om law system.
