1.3 ELECTRIC FIELD
-
An electric field, E is a region in which an electric force will act on a charge when the charge is
placed in the region.

1.4 ELECTRIC POTENTIAL
Electric potential at a point, V is defined as the work done per unit charge to bring a test charge from infinity to that point in an electric field produced by a source point charge, Q
-
If the electric potential at a point in an electric field is V, then a charge q at that point has electric potential energy, U of
Potential Difference
Vba = Vb – Va (final – initial)
