Question

what is Ohm's law. please someone give me the answer ​

Answer 1

The potential difference in a circuit is directly proportional to the current flowing through it

Answer 2

Ohm's Law :

Ohm's law states that the current (I) passing through a conductor is directly proportional to the potential difference (V) across its ends, provided the physical conditions like temperature, density, etc. remains unchanged.

Mathematically :

Potential difference ∝ Current

or

Potential difference = Resistance × Current

or

V ∝ I

or

V = RI

Here, Resistance (R) is a constant.⠀ ⠀⠀ ⠀ ⠀⠀ ⠀

@ItsFadedStar booster :

Resistance : It is a property of conductor by virtue of which it opposes the flow of current through it. It is equal to the ratio of the potential difference applied across its ends and the current flowing through it

$\sf Resistance = \dfrac{Potential \: difference}{Current}$

or

$\sf R = \dfrac{V}{I}$
