FAQs on Quick Revision: Electrostatic Potential & Capacitance - Physics for JAMB

1. What is electrostatic potential?
Ans. Electrostatic potential is the amount of work done in bringing a unit positive charge from infinity to a point in an electric field. It is measured in volts (V) and represents the potential energy per unit charge at a given point.
2. How is electrostatic potential different from electric potential energy?
Ans. Electrostatic potential refers to the potential energy per unit charge at a point in an electric field, while electric potential energy is the potential energy of a charged object in an electric field. The main difference is that electrostatic potential is a property of the electric field itself, whereas electric potential energy depends on the interaction between the charged object and the electric field.
3. What is 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 on one of the conductors of a capacitor to the potential difference between the conductors. Capacitance is measured in farads (F).
4. How does the shape of a capacitor affect its capacitance?
Ans. The shape of a capacitor determines its capacitance. A capacitor with larger surface area and smaller separation between its conductors will have a higher capacitance compared to a capacitor with smaller surface area and larger separation. The shape affects the electric field distribution and the amount of charge that can be stored.
5. How can the capacitance of a capacitor be increased?
Ans. The capacitance of a capacitor can be increased by increasing the surface area of its conductors, decreasing the separation between the conductors, or by using a material with a higher permittivity (dielectric constant) between the conductors. These factors increase the amount of charge that can be stored and thus increase the capacitance.
