Physics - Capacitance

Practise 18 JEE Advanced previous year questions on Capacitance, compiled from papers spanning 2007 to 2026. Each question is pulled directly from the actual exam paper it appeared in, so you're practising in the exact style and difficulty JEE Advanced tests.

Capacitance has been asked in 15 of the 27 years of JEE Advanced papers analysed (2000–2026), with 18 questions in all. 6% of them were easy, 72% moderate and 22% tough. Most of its questions came from 2022, with 2 questions that year. In the last three years (2024–2026) it had 2 questions across 6 papers, about 0.3 per paper.

The chapter's 5 topics are not weighted equally: Capacitors with Dielectric (5 questions, 28%), Charging and Discarging of capacitors (4 questions, 22%), and Force and Energy stored in capacitor (4 questions, 22%) have been asked the most. Capacitors with Dielectric has also led over the last five years, with 2 questions. Capacitors with Dielectric has produced the most tough questions (3).
