What is ohm’s law definition in Physics

Ohm’s law definition

 

The current passing through a conductor is directly proportional to the potential difference across the end points of the conductor.

 

Mathematical Form:

 

According to this law:

V < I (< represents the sign of proportionality. Do not write this in your examination}

 

=> V = IR

 

Where R is a constant is called the resistance of the conductor,

 

Fortunately, now, to do this, you do not have to go to the library or the nearest bookstore in search of your favorite work. Modern humanity has found a new way to solve this problem – e-books… Probably few people know that the first prototype of an e-book appeared relatively recently in 1971 in the United States, when it became necessary to replicate the Declaration of Independence. During this time, e-books have undergone a number of changes in external design, and in the internal electronic performance, and in software.
