## FAQs on Introduction to Electrostatic Potential & Capacitance Video Lecture - Physics for JEE Main & Advanced

 1. What is electrostatic potential?
Ans. Electrostatic potential refers to the amount of electric potential energy that a charged particle possesses at a specific point in an electric field. It represents the work done in bringing a positive test charge from infinity to that point in the field.
 2. How is electrostatic potential different from electric potential energy?
Ans. Electric potential energy is the potential energy associated with a charged particle due to its position relative to other charged particles, while electrostatic potential is the potential energy per unit charge at a specific point in an electric field. In other words, electric potential energy depends on the charges and their positions, while electrostatic potential depends on the electric field at a specific point.
 3. What is the concept of capacitance?
Ans. Capacitance is a measure of a capacitor's ability to store electrical energy in an electric field. It is defined as the ratio of the magnitude of the charge stored on one of the capacitor's plates to the potential difference across the plates.
 4. How is capacitance related to the size and shape of a capacitor?
Ans. The capacitance of a capacitor is directly proportional to the surface area of its plates and inversely proportional to the distance between the plates. Therefore, increasing the surface area or decreasing the distance between the plates will increase the capacitance of the capacitor.
 5. What is the formula to calculate the capacitance of a parallel-plate capacitor?
Ans. The capacitance (C) of a parallel-plate capacitor is calculated using the formula C = ε₀A/d, where ε₀ is the permittivity of free space, A is the surface area of one of the plates, and d is the distance between the plates.
