Can there be an electric field inside an insulator?

  • #1
Just as the title asks, I wonder if there can be any electric field inside an insulator when a point change is placed near it. If so, why?

Why wouldn't there be?

That is what defines an insulator. It is a material whose charges are tightly bound, so they don’t drift away even under high E fields.

Electricity is everywhere. The only question is if the amount is large enough to do any thing or not. Example: A spark can't do much but if you have an area that is charged, then you got something. Bottom line, electricity in some form or another exists everywhere.

And since electric fields are zero in a conductor, if they were zero in insulators, there wouldn't be much point in talking about them.
