Physics - Capacitance
Practise 24 WBJEE previous year questions on Capacitance, compiled from papers spanning 2009 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 WBJEE tests.
Capacitance has been asked in 16 of the 18 years of WBJEE papers analysed (2009–2026), with 24 questions in all. 33% of them were easy, 50% moderate and 17% tough. Most of its questions came from 2014, with 3 questions that year. In the last three years (2024–2026) it had 2 questions across 3 papers, about 0.7 per paper.
The chapter's 6 topics are not weighted equally: Grouping of capacitors (12 questions, 50%), Force and Energy stored in capacitor (5 questions, 21%), and Capacitance (3 questions, 13%) 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).
