Question

What is resistance of a conductor and cause of resistance.

Answer 1

when an electric current flows through a conductor such as a metal wire, the moving electrons can collide with the ions in the metal. This makes it more difficult for the current to flow, and causes resistance.

Answer 2

$\textbf{Hey there}$!

$\textbf{Answer}$:

$\underline{\textbf{Resistance}}$:

$<b>$

Resistance of a conductor is defined as the ratio of the potential difference applied across the conductor to the current flowing through it

Mathematically,

R = V/I

$\textbf{\underline{Units \:of \:Resistance}}$:

The SI unit of a conductor is ohm.


It is denoted by ( Ω ).


$\underline{\textbf{Cause\: Of \:Resistance}}$:


The resistance of a conductor implies the opposition, which the conductor offers to the flow of charge through it. When a potential difference is applied across a conductor, an electric field is set up across its two ends.

Due to this, the free electrons gets accelerated. As the electrons move, they collide against the ions and atoms and their motion is thus opposed. This opposition offered by the ions and atoms is termed as the resistance of the conductor.
