Detailed explanation-1: -According to Ohm’s law, the electric current flowing through a conductor is directly proportional to the potential difference across the ends of a conductor provided temperature and other physical conditions remain same.
Detailed explanation-2: -Ohm’s law states that the voltage across a resistance is directly proportional to the current flowing in it.
Detailed explanation-3: -I=V/R, from this equation it’s clear that I is directly proportional to V and inversely proportional to R.
Detailed explanation-4: -Ohms Law states that the current through a conductor between two points is directly proportional to the potential difference across its ends. Mathematically, the law states that V = IR, where V is the potential difference or voltage, I is the current, and R is the resistance of the conductor.
