Question

what is ohm's law? write its derivation

Answer 1

▶️The main derivation of ohm's law is
$v = ir$
And it was given by ohm.
It is current flowing through a conductor between two points is directly proportional to the voltage across the two points.

❤️ Hope it helps ❤️

Answer 2

• Ohm's law states that at a constant temperature, current I through a conductor between two points is directly proportional to the potential difference or voltage, V, across the two points. Thus, the ratio V: I is constant, and is called the resistance, R, of the conductor.
