Explanation:
Detailed explanation-1: -Ohm () is the unit of resistance. One ohm is defined as that resistance of an object when a current of 1 ampere flows through an object having a voltage(potential difference) of 1 Volt.
Detailed explanation-2: -One-ohm is equal to 1 volt / 1 ampere. The SI unit of electrical resistance i.e Ohm is named in honour of the 19th-century German physicist Georg Simon Ohm.
Detailed explanation-3: -Ohm defines the unit of resistance of “1 Ohm” as the resistance between two points in a conductor where the application of 1 volt will push 1 ampere, or 6.241×10^18 electrons. This value is usually represented in schematics with the greek letter “", which is called omega, and pronounced “ohm".
