AI Thread Summary
The quantity "P" in the equation D = ε0E + P represents the Polarization or the Polarization vector. This term is crucial in understanding electric displacement in materials. It accounts for the alignment of dipoles within a dielectric material when subjected to an electric field. Clarifying this concept is essential for grasping the behavior of electric fields in different media. Understanding "P" enhances comprehension of electric displacement theory.

What is the name of the quantity "P"?

I tried to learn Electric Displacement "D". I think I have fairly understood it. But there's one thing that is nagging me. The quantity "P".

On the link - http://www.daviddarling.info/encyclopedia/E/electric_displacement.html" - I read the equation : D = ε0E + P. In this what does "P" stand for?

Please help.

Regards,

It's usually called the Polarization or the Polarization vector.
 


Thanks!

So I know that electrons are fundamental, there's no 'material' that makes them up, it's like talking about a colour itself rather than a car or a flower. Now protons and neutrons and quarks and whatever other stuff is there fundamentally, I want someone to kind of teach me these, I have a lot of questions that books might not give the answer in the way I understand. Thanks
