Physics - Capacitance

Practise 47 TS EAMCET previous year questions on Capacitance, compiled from papers spanning 2001 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 TS EAMCET tests.

Capacitance has been asked in 19 of the 24 years of TS EAMCET papers analysed (2001–2024), with 47 questions in all. 28% of them were easy, 57% moderate and 15% tough. Most of its questions came from 2024, with 5 questions that year. In the last three years (2022–2024) it had 13 questions across 17 papers, about 0.8 per paper.

The chapter's 5 topics are not weighted equally: Grouping of capacitors (13 questions, 28%), Charging and Discarging of capacitors (11 questions, 23%), and Force and Energy stored in capacitor (8 questions, 17%) have been asked the most. Grouping of capacitors has also led over the last five years, with 8 questions. Charging and Discarging of capacitors has produced the most tough questions (2).
