Høla guys!! ❤

Please give the correct explanation of Ohm's law!! ​

Answer 1

Explanation:

Answer :-

Step-by-step explanation :-

Ohm's law .

→ Ohm's law gives a relationship between current and potential difference .

→ According to Ohm's law : At constant temperature , the current flowing through a conductor is directly proportional to the potential difference across its end .

→ If I is the current flowing through a conductor and V is the potential difference ( or voltage ) across its ends , then according to Ohm's law :

$I \propto V$( At constant temperature ) .

This can also be written as : $V \propto I$

Or V = R × I .

Where R is a constant called “resistance” of the conductor .

★ Resistance of a conductor : The property of a conductor due to which it opposes the flow of current through it is called resistance .

→ The resistance of a conductor depends on length, thickness, nature of material and temperature of the conductor.

→ The SI unit of resistance is ohm( Ω ) .

Answer 2

Definition of Ohm's Law

The potential difference , V , across the ends of a metallic wire in an electric circuit is directly proportional to the current flowing through it , provided its temperature is constant. This is called Ohms law.

Mathematical Expression

$\dashrightarrow \rm V \infty I \\\\ \rm \dashrightarrow \dfrac{V}{I}= Constant \\\\ \rm \dashrightarrow \dfrac{V}{I} = R \\\\ \rm \dashrightarrow V = IR$

Here ,

R is the resistance

V is the potential difference

I is the current flowing through conductor

More Information about Ohm's Law

On the basis of his experiment observations, a German physicist George Simon Ohm derived a relationship between electric current and potential difference in 1828. This relationship is know as Ohm's law
