Practise 30 JEE Advanced previous year questions on Current Electricity, compiled from papers spanning 2006 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 JEE Advanced tests.
Current Electricity has been asked in 14 of the 27 years of JEE Advanced papers analysed (2000–2026), with 30 questions in all. 13% of them were easy, 73% moderate and 13% tough. Most of its questions came from 2010, with 6 questions that year. In the last three years (2024–2026) it had 2 questions across 6 papers, about 0.3 per paper.
The chapter's 8 topics are not weighted equally: Electric Power and Heating Effect of Current (7 questions, 23%), Wheatstone Bridge (6 questions, 20%), and Resistance and Resistivity (5 questions, 17%) have been asked the most. Over the last five years the most frequent topics have been Electric Current and Drift of Electrons (1), Wheatstone Bridge (1), and Electric Power and Heating Effect of Current (1). Electric Power and Heating Effect of Current has produced the most tough questions (1).
