Question

what is the Ohm's law? Explain it.​

Answer 1

Answer:

ohm 's law state that potential difference = Resistance × Current .

so , V = IR.

it is derived as :-

V is directly proportional to I

so , when we remove proportionality sign , we add a constant called R. resistance

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

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