Physics - Capacitance
Practise 5 IAT (IISER) previous year questions on Capacitance, compiled from papers spanning 2019 to 2025. Each question is pulled directly from the actual exam paper it appeared in, so you're practising in the exact style and difficulty IAT (IISER) tests.
Capacitance has been asked in 3 of the 9 years of IAT (IISER) papers analysed (2017–2026), with 5 questions in all. 0% of them were easy, 100% moderate and 0% tough. Most of its questions came from 2021, with 2 questions that year. In the last three years (2023–2026) it had 1 question across 3 papers, about 0.3 per paper.
The chapter's 3 topics are not weighted equally: Grouping of capacitors (3 questions, 60%), Charging and Discarging of capacitors (1 question, 20%), and Capacitance (1 question, 20%) have been asked the most. Grouping of capacitors has also led over the last five years, with 2 questions.
