Physics - Current Electricity

Practise 134 TS EAMCET previous year questions on Current Electricity, 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.

Current Electricity has been asked in 24 of the 24 years of TS EAMCET papers analysed (2001–2024), with 134 questions in all. 51% of them were easy, 41% moderate and 8% tough. Most of its questions came from 2020, with 17 questions that year. In the last three years (2022–2024) it had 33 questions across 17 papers, about 1.9 per paper.

The chapter's 8 topics are not weighted equally: Resistance and Resistivity (35 questions, 26%), Electric Instruments (23 questions, 17%), and Combination of Resistances (18 questions, 13%) have been asked the most. Resistance and Resistivity has also led over the last five years, with 16 questions. Wheatstone Bridge has produced the most tough questions (4).
