Electric potential is the amount of work needed to move a unit positive charge from one point to another in an electric field. It is measured in volts (V) and is a measure of the electric potential energy per unit charge.
A capacitor is a device that stores electrical energy in an electric field. It consists of two conductive plates separated by an insulating material (dielectric). When a voltage difference is applied across the plates, it creates an electric field, which causes the plates to store energy.
The electric potential of a capacitor can be calculated by dividing the charge on one plate by the capacitance of the capacitor. This can be represented by the equation V = Q/C, where V is the electric potential, Q is the charge, and C is the capacitance.
Electric potential is a scalar quantity that measures the amount of electric potential energy per unit charge at a point in an electric field. On the other hand, electric field is a vector quantity that measures the force per unit charge at a point in an electric field. Electric potential is dependent on the electric field, but electric field is not dependent on the electric potential.
When a capacitor is connected to a battery, the electric potential difference between the plates of the capacitor increases. This is because the battery provides a constant voltage, causing the plates of the capacitor to store more energy. The electric potential difference will remain constant as long as the capacitor is connected to the battery.
