Current Electricity

Drift velocity, Ohm's law, resistivity, cells with internal resistance, Kirchhoff's laws, and the Wheatstone bridge run through this chapter. It is one of NEET's most numerical-heavy areas, full of circuit solving, equivalent resistance, and power dissipation.

Weightage: what the paper actually did

Current Electricity carried 4 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.

Question 1 · NEET 2026

A room heater is rated 400 W, 220 V. If the supply voltage drops to 200 V, what will be the power consumed (approximately)?
  1. A.200 W
  2. B.400 W
  3. C.331 W
  4. D.121 W
Answer and explanation

Answer: C

The heater resistance is fixed, so P=V2/RP = V^2/R gives Pc=(VV0)2P0=(200220)2×400≈331P_c = \left(\frac{V}{V_0}\right)^2 P_0 = \left(\frac{200}{220}\right)^2 \times 400 \approx 331 W. Power scales as the square of voltage, not linearly, so B (unchanged) and A (linear scaling) are wrong, and D over-reduces. Why the other options are wrong: - (A) Assumes linear halving rather than square scaling. - (B) Assumes power unchanged with voltage. - (D) Over-applies the square factor.

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 12-question mock on the exam screen.

Questions

How many questions did Current Electricity have in NEET 2026?

Current Electricity carried 4 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?

In the BrainIt app, free until the 2027 exam: its bank holds 50,000 past NTA questions tagged to all 83 chapters, including this one, with accuracy tracked per chapter. A sample question from this chapter is 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.
