This is possible because each charge makes an electric field around itself.

This is possible because they are given potential energy by the electric field.

He was already there; she knew by the way the air had taken a charge around her body, an electric field.

The treatment given so far is for a system not subject to an external electric field.

But why did we get a reasonable result for the electric field?

The potential may be obtained from the electric field as.

The electric field between the plates is then, and the potential.

The electric field itself may be found from the equations.

Thus the general form for the electric field is as follows.

What can we say about the line integral of the electric field?
