Physics - Capacitance

Practise 33 KCET 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 KCET tests.

Capacitance has been asked in 19 of the 20 years of KCET papers analysed (2007–2026), with 33 questions in all. 33% of them were easy, 45% moderate and 21% tough. Most of its questions came from 2021, with 4 questions that year. In the last three years (2024–2026) it had 3 questions across 3 papers, about 1 per paper.

The chapter's 5 topics are not weighted equally: Grouping of capacitors (15 questions, 45%), Force and Energy stored in capacitor (7 questions, 21%), and Capacitors with Dielectric (5 questions, 15%) have been asked the most. Grouping of capacitors has also led over the last five years, with 2 questions. Grouping of capacitors has produced the most tough questions (2).
