explain ohms law.and the scientist who introduced it
Answers
Answer:
Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points. ... More specifically, Ohm's law states that the R in this relation is constant, independent of the current.
Georg Simon Ohm (/oʊm/,[1] German: [ˈɡeːɔʁk ˈʔoːm];[2][3] 16 March 1789 – 6 July 1854) was a German physicist and mathematician. As a school teacher, Ohm began his research with the new electrochemical cell, invented by Italian scientist Alessandro Volta. Using equipment of his own creation, Ohm found that there is a direct proportionality between the potential difference (voltage) applied across a conductor and the resultant electric current. This relationship is known as Ohm's law.
➡The potential difference across the ends of the terminal of the metallic wire is directly proportional to the current flowing through it ,at constant temperature.
