The electric field is the fundamental concept for electric phenomena. It also helps to visualize the fact that charges can exert forces on each other without being in contact.

These are representations of the existence of the electric field near a positively-charged sphere (a) and a negatively-charged sphere (b). In these images, the arrows merely indicate the …

What is an Electric Field ? It is a concept used to describe how electric forces will act on a charged particle in space.

In this module, we will explore the concept of the electric field and the usefulness of equipotential surfaces. Unless otherwise instructed, answer all questions in your lab notebook, including …

Field Lines (Lines of force) Electric field lines (lines of force) are continuous lines whose direction is everywhere that of the electric field

The Electric Field Due to Point Charges We have now reduced the problem of figuring out what a charge will do, to a problem of finding the field that it feels. The next step is to develop …

An electric field once established by a positive or negative charge extends in all directions from the charge. Thus, it can exist in empty space if that is what surrounds the charge.
