Physics - Capacitance

Practise 29 VITEEE previous year questions on Capacitance, compiled from papers spanning 2006 to 2023. Each question is pulled directly from the actual exam paper it appeared in, so you're practising in the exact style and difficulty VITEEE tests.

Capacitance has been asked in 16 of the 18 years of VITEEE papers analysed (2006–2024), with 29 questions in all. 21% of them were easy, 48% moderate and 31% tough. Most of its questions came from 2008, with 4 questions that year. In the last three years (2022–2024) it had 3 questions across 2 papers, about 1.5 per paper.

The chapter's 5 topics are not weighted equally: Grouping of capacitors (8 questions, 28%), Capacitors with Dielectric (7 questions, 24%), and Force and Energy stored in capacitor (7 questions, 24%) have been asked the most. Over the last five years the most frequent topics have been Charging and Discarging of capacitors (2), Capacitors with Dielectric (1), and Grouping of capacitors (1). Force and Energy stored in capacitor has produced the most tough questions (4).
