How to imagine an electric field?

    Is it 2 dimensional or 3 dimensional?

    Hi SELFMADE! :smile:
    Space is 3 dimensional, so any field is 3 dimensional.

    Did you have a specific electric field in mind?

    EDIT: just occurred to me …

    if a field was 2 dimensional, it would fall off as 1/r instead of 1/r2, since it would spread out over a circle (~ r) instead of a sphere (~ r2) :wink:
