Question

what is ohm's law and also write the S.I units for ohm's law​

Answer 1

Ohm's law says that in an electrical circuit, the current passing through a resistor between two points, is related to the voltage difference between the two points, and are related to the electrical resistance between the two points.

SI unit is Ohm (Ω).

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.⠀

SI Unit :

Ohm (Ω)

@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

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