## Definition of Electric Field and Electric Potential

The electric field is a field that surrounds a charged particle or an electric charge distribution. It represents the force that would be experienced by another charged particle placed within the field. The electric field is a vector quantity and is defined as the force per unit charge.

Electric potential, also known as voltage, is the measure of the potential energy per unit charge available in an electric field. It is a scalar quantity and is defined as the energy required to move a unit charge from one point to another within the electric field. The electric potential at a point in space is directly proportional to the potential energy of a unit charge placed at that point.
