An electric field is a physical field that surrounds an electrically charged object. It is a force field that affects the movement and behavior of other charged particles within its vicinity.
Electric field strength is measured in newtons per coulomb (N/C) or volts per meter (V/m). This measures the force exerted on a unit charge placed within the electric field.
Electric potential is the amount of work required to move a unit charge from one point to another in an electric field. The strength of the electric field is directly proportional to the electric potential.
The direction of an electric field is always in the direction in which a positive test charge would move. The direction of electric potential is the direction in which a positive test charge would move to decrease its potential energy.
Electric potential is the amount of potential energy per unit charge at a given point in an electric field. Electric potential energy is the energy that a charged particle has due to its position in an electric field. Electric potential is a scalar quantity, while electric potential energy is a vector quantity.
