Question

State Ohms law. The potential difference between terminals of an electric heater is 250V, when it draws a current of 10A. What current will the heater draw, if the potential difference is increased to 300V

Answer 1

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

Ohm's law may be expressed mathematically as V/I = R. That the resistance, or the ratio of voltage to current, for all or part of an electric circuit at a fixed temperature is generally constant had been established by 1827 as a result of the investigations of the German physicist Georg Simon Ohm.
