Question

define Ohm law and write about?

Answer 1

According to Ohms law at constant temperature the current flowing through a wire is directly proportional to the potential difference

V=IR

Answer 2

Ohm's law is a law that states that the voltage across a resistor is directly proportional to the current flowing through the resistance. Ohm's law is named for German physicist Georg Ohm (1789-1854). A simple formula, Ohm's law, is used to show the relationship of current, voltage, and resistance.
