Current Electricity: NEET previous year questions

34 questions in ten years of NEET, asked in 10 of 10 years. Here is what this chapter tests and how.

Asked in 10 years: 34; 10 of 10 papers
10-year average: 3.2; a paper · 2.5 since 2024 -1.0
Typical range: 2–5; questions a paper; fewest 1, most 5
Weighted estimate: 3.1; model, recent papers count more · about 12 marks

Typical range (fact)
10-year average (fact)
Weighted estimate (model)

Typical range: questions per paper in the middle eight of the ten papers, leaving out the single highest and lowest year (about the 10th to 90th percentile), each paper scaled to 180 questions. The ten-year average and the range are historical fact. The weighted estimate is a model: each paper's share, with recent papers counting more (half-life three years), and dropped syllabus removed. It is a guide to effort, not a forecast.

Coverage

How much of the chapter NEET has used

We split the chapter into 171 ideas. In ten years NEET built a question around 23 of them. Most of the chapter has never been asked, which is why learning it whole beats memorising past questions.

Asked as the main idea: 23
Touched on in a question: 11
Never asked: 137

Ohm's Law and Resistance
Expect a short numerical problem (one or two formula steps, four numeric options) about Ohm's Law and Resistance; a diagram-based item (read or label a figure/graph, then answer) is the next most likely shape. Past framings centre on: numerical; resistor colour code reading.
