Physics - Capacitance
Practise 20 AIIMS previous year questions on Capacitance, compiled from papers spanning 2001 to 2019. Each question is pulled directly from the actual exam paper it appeared in, so you're practising in the exact style and difficulty AIIMS tests.
Capacitance has been asked in 13 of the 19 years of AIIMS papers analysed (2001–2019), with 20 questions in all. 30% of them were easy, 40% moderate and 30% tough. Most of its questions came from 2019, with 4 questions that year. In the last three years (2017–2019) it had 9 questions across 5 papers, about 1.8 per paper.
The chapter's 5 topics are not weighted equally: Charging and Discarging of capacitors (6 questions, 30%), Grouping of capacitors (5 questions, 25%), and Capacitors with Dielectric (4 questions, 20%) have been asked the most. Grouping of capacitors has produced the most tough questions (3).
