Question

pls tell me about relative permitivity .........if no say hello
​

Answer 1

Hey friend...

Here is your answer...

Relative permitvity is the ratio of permitvity of the medium to the permitvity of vacuum(air).

Expression :-

Er=Em/Eo

Er=relative permitvity

Em=permitvity of medium

Eo= permitvity of vacuum.

HOPE that it will help you ✌️ ✌️

Answer 2

The relative permittivity of a material is its permittivity expressed as a ratio relative to the vacuum permittivity. Permittivity is a material property that affects the Coulomb force between two point charges in the material.
