State Ohm's law . Ohm's law states that the electric current flowing through a metallic wire is directly proportional to the potential difference V across its ends provided its temperature remains the same. Ohm 's Law was given by German physicist Georg Simon Ohm . It states the relationship between current, resistance, and voltage across an electrical circuit. This relationship between current I, voltage V, and resistance R was given by famous German scientist Georg Simon Ohm in 1827. He found conducting his experiment that the product of the current flowing through the conductor and the resistance of the conductor determines the voltage drop over that conductor in the circuit. In this article ... Ohm’s law is one of the most popular and important laws that helps us define the relationship between voltage, current and resistance. The law was first established by a German physicist named Georg Simon Ohm , and was the most important theory to describe the quantitative characteristics of the physics of electricity. State Ohm'S Law . What Are Its Limitations?According to Ohm's law , the current flowing in a conductor is directly proportional to the potential difference across its ends provided the physical conditions and temperature of conductor remains constant. Limitations of Ohm's law : 1. Ohm's law does not apply to conductors such as diode, radio valves, metal rectifiers, where electricity passes through gases. 2. Ohm's law is applicable only when the physical conditions remain constant. 3. Ohm's law ...
