Voltage: Voltage is another term for electric potential difference, which measures the change in electric potential energy per unit charge between two points in an electrical circuit.
Capacitance:Capacitance refers to an object's ability to store electrical energy in an electric field. It depends on both geometry and material properties.
Equipotential Surfaces: Equipotential surfaces are imaginary surfaces where all points have equal electric potentials. They are perpendicular to electric field lines and help visualize regions with constant potentials.
