Physics - Current Electricity

Practise 52 Manipal (MET) previous year questions on Current Electricity, compiled from papers spanning 2010 to 2024. Each question is pulled directly from the actual exam paper it appeared in, so you're practising in the exact style and difficulty Manipal (MET) tests.

Current Electricity has been asked in 15 of the 15 years of Manipal (MET) papers analysed (2010–2024), with 52 questions in all. 60% of them were easy, 37% moderate and 4% tough. Most of its questions came from 2018, with 8 questions that year. In the last three years (2022–2024) it had 3 questions across 3 papers, about 1 per paper.

The chapter's 9 topics are not weighted equally: Electric Instruments (14 questions, 27%), Electric Power and Heating Effect of Current (9 questions, 17%), and Combination of Resistances (7 questions, 13%) have been asked the most. Over the last five years the most frequent topics have been Electric Power and Heating Effect of Current (5), Electric Current and Drift of Electrons (2), and Resistance and Resistivity (2).
