Do Electric fields really contain energy in them? [closed]
$begingroup$ I see your question has a close vote due to lack of clarity. I think I understand what you are trying to ask, but try adding more words to make it more clear.

How does an electric field store energy?
Similarly, the electric field stores the energy for any electrostatic set up. Leaving the analogy, we also have an attractive force when we have particles of opposite charges, which means that the 'springs' pull in rather than push out. Energy stored in an electric field - Means the Potential Energy (electric) in that space.
