A Physics chapter of the NEET syllabus, and how to practise it for the computer-based exam.

Exam rules change between cycles. Confirm dates, syllabus and pattern against NTA's official site. We are not NTA.

Weightage: what the paper actually did

Current Electricity carried 5 questions in the NEET 2026 paper. One paper is a data point, not a destiny: NTA moves weight between chapters every cycle, which is why the weightage tables deserve care. The stable facts are the paper's shape: 180 questions, 720 marks, +4 right, −1 wrong.

Sample PYQs from this chapter

Real questions NTA asked from Current Electricity, with the answer and the working. Try before you peek.

Question 1 · NEET 2020

The solids which have the negative temperature coefficient of resistance are:
  1. A.insulators only
  2. B.semiconductors only
  3. C.insulators and semiconductors
  4. D.metals
Answer and explanation

Answer: C

Metals have a positive temperature coefficient of resistance, while insulators and semiconductors have a negative temperature coefficient of resistance. This is due to the increase in carrier concentration in insulators and semiconductors with temperature. Chapter: Current Electricity.

Question 2 · NEET 2020

A charged particle having drift velocity of 7.5 × 10⁻⁴ m s⁻¹ in an electric field of 3 × 10⁻¹⁰ V m⁻¹ has a mobility in m² V⁻¹ s⁻¹ of
  1. A.2.5 * 106^{6}
  2. B.2.5 * 10−^{-}6^{6}
  3. C.2.25 * 10−^{-}1^{1}5^{5}
  4. D.2.25 * 101^{1}5^{5}
Answer and explanation

Answer: A

Mobility μ\mu is given by μ=vdE\mu = \frac{v_d}{E}, where vdv_d is the drift velocity and EE is the electric field. Substituting the values, μ=7.5∗10−43∗10−10=2.5∗106 m2V−1s−1\mu = \frac{7.5 * 10^{-4}}{3 * 10^{-10}} = 2.5 * 10^6\ m^2V^{-1}s^{-1}. Chapter: Current Electricity.

How to practise Current Electricity

Chapter by chapter, against real past-paper questions, on a screen: NEET is computer based from 2027. Read the chapter once, then attempt its PYQs until your accuracy stops climbing, and let the wrong answers tell you which lines to reread. If the chapter keeps refusing to stick, that has its own guide. There is also a free NEET mini mock with answers.

Questions

How many questions did Current Electricity have in NEET 2026?

Current Electricity carried 5 questions in the NEET 2026 paper. Weightage shifts between cycles, so treat it as a probability, not a promise.

Where can I practise Current Electricity PYQs for NEET?

Explore available chapter-wise NEET practice in BrainIt, free until the 2027 exam. Review explanations and track chapter accuracy to guide your revision. Sample questions from this chapter are on this page.

Is Current Electricity important for NEET 2027?

It is part of the Physics syllabus the paper draws from, and NEET 2027 is computer based, so practise it on a screen. Your own accuracy in the chapter matters more than any weightage table: a heavy chapter you already score well on needs less time than a light one you keep missing.
