In JEE Advanced Physics, Capacitance is a topic which is considered to be a moderate topic, carrying a weightage of around 6% with 2-3 questions asked each year. Most of the questions are conceptual based which focuses on capacitors.
A capacitor is a combination of two conductors placed close to each other. It is used to store energy electrostatically in an electric field. The ‘non-conducting’ dielectric acts to increase the capacitor’s charge capacity. Capacitors are widely used as parts of electrical circuits in many common electrical devices.
