Physics - Capacitance

Practise 5 NEST (NISER) previous year questions on Capacitance, compiled from papers spanning 2014 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 NEST (NISER) tests.

Capacitance has been asked in 5 of the 16 years of NEST (NISER) papers analysed (2011–2026), with 5 questions in all. 0% of them were easy, 60% moderate and 40% tough. Most of its questions came from 2025, with 1 question that year. In the last three years (2024–2026) it had 1 question across 4 papers, about 0.3 per paper.

The chapter's 3 topics are not weighted equally: Capacitance (2 questions, 40%), Charging and Discarging of capacitors (2 questions, 40%), and Grouping of capacitors (1 question, 20%) have been asked the most. Capacitance has also led over the last five years, with 1 question. Capacitance has produced the most tough questions (1).

Frequently Asked Questions

1.How many questions are available for Capacitance?

This chapter includes 5 questions compiled from NEST (NISER) papers spanning 2014 to 2025.

2.Are these questions only from NEST (NISER), or from other exams too?

These are NEST (NISER) questions specifically for the Capacitance chapter. Questions from other exams like JEE Main or NTA Abhyas (JEE Main) are organised separately under their respective exam sections.

3.Is Capacitance an important chapter for NEST (NISER) Physics?

Capacitance has appeared in 5 of the 16 years of NEST (NISER) papers covered here, with 5 questions across 5 papers - about one per paper it appears in.

4.What is the difficulty level of Capacitance questions in NEST (NISER)?

Of the 5 questions analysed for this chapter, 0% are easy, 60% moderate and 40% tough. 2025 had the most, with 1 question.

5.Which topics in Capacitance should I focus on?

These topics have carried the most weightage in Capacitance:

  • Capacitance - 2 questions (40%)
  • Charging and Discarging of capacitors - 2 questions (40%)
  • Grouping of capacitors - 1 question (20%)
  • Capacitance has produced the most tough questions (1).
6.Is Capacitance's weightage in NEST (NISER) going up or down?

Across all 5 papers analysed, Capacitance has averaged about 1.0 questions per paper. In the last three years (2024–2026), that average has fallen, at about 0.3 questions per paper. Use the year-wise numbers on this page for the exact trend before you decide how much time to give it.
