An electric field is a region in which electrically charged particles experience a force. It is created by electric charges and exerts a force on other charges in its vicinity.
The electric field can change in two ways: through the movement of electric charges or through a change in the distribution of charges. The strength and direction of the electric field can also change depending on the position in the field.
Potential is a measure of the electrical potential energy per unit charge at a specific point in space. In other words, it describes the amount of work that would be needed to move a unit of electric charge from that point to a reference point.
The electric potential energy of a charged particle is directly proportional to its charge and the potential difference between two points in an electric field. This means that a higher potential difference between two points results in a higher potential energy for the particle.
A change in electric field can result in a change in the potential at a point in space. For example, if the electric field becomes stronger, the potential at a point in the field will decrease. Similarly, if the electric field becomes weaker, the potential at a point in the field will increase.
