Question

what is ohm's law and it's formula​

Answer 1

Answer:

ohm's law state that.... voltage across the conductor is directly proportional to the current flowing through the conductor when all the physical condition remains constant (like force, temp., and pressure).

V is directly proportional to I

V = IR

here R is resistance i.e. constant to remove proportionality sign.

Answer 2

Answer:

The potential difference across two end of the conductor is directly proportional to the current flowing through it if temperature remains constant.

Mathematicaly - I directly proportional V

IR=V

where R is constant for resistance
