Electric Field: The region surrounding a charged object where other charged objects experience a force. The electric field describes the strength and direction of the force acting on a test charge at any point in space.
Coulomb's Law: The physical law that describes the force of attraction or repulsion between two stationary, electrically charged objects. The force is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.
Capacitance: The ability of a capacitor to store an electric charge. Capacitance is determined by the physical characteristics of the capacitor, such as the area of the plates and the distance between them.
