Physics - Capacitance

Practise 18 BITSAT previous year questions on Capacitance, compiled from papers spanning 2009 to 2024. Each question is pulled directly from the actual exam paper it appeared in, so you're practising in the exact style and difficulty BITSAT tests.

Capacitance has been asked in 14 of the 16 years of BITSAT papers analysed (2009–2024), with 18 questions in all. 33% of them were easy, 50% moderate and 17% tough. Most of its questions came from 2023, with 2 questions that year. In the last three years (2022–2024) it had 3 questions across 3 papers, about 1 per paper.

The chapter's 5 topics are not weighted equally: Grouping of capacitors (7 questions, 39%), Capacitors with Dielectric (4 questions, 22%), and Force and Energy stored in capacitor (3 questions, 17%) have been asked the most. Grouping of capacitors has also led over the last five years, with 2 questions. Capacitors with Dielectric has produced the most tough questions (3).
