NEET 2020 Physics Current Electricity Questions
Use this page to connect the official 2020 paper with current Physics practice. NeetVellum does not claim a chapter appeared in that paper until the official question and final key have been mapped.
What to master
circuits, cells, resistance combinations, metre bridges and electrical power.
Original practice preview
These are current-syllabus NeetVellum questions, shown separately from historical-paper provenance.
Example 2 · difficulty 2/5
A uniform electric field in a metallic conductor points along the positive x-direction. Which statement correctly gives the directions of electron drift and conventional current density?
- A. Both point along the negative x-direction.
- B. Electron drift is along negative x, while conventional current density is along positive x.
- C. Electron drift is along positive x, while conventional current density is along negative x.
- D. Both point along the positive x-direction.
Example 3 · difficulty 3/5
Consider the following statements for a metal when number density n, electron charge magnitude e and electron mass m remain fixed: I. Increasing relaxation time increases conductivity. II. Increasing relaxation time decreases resistivity. Which option is correct?
- A. Only statement I is correct.
- B. Only statement II is correct.
- C. Both statements I and II are correct.
- D. Neither statement I nor statement II is correct.
The evidence-first practice loop
- 1. Verify provenanceOfficial paper and final key before accepting a PYQ label.
- 2. Attempt closed-bookExpose the concept or execution gap before rereading.
- 3. Repair and returnClassify the miss and re-practice after a delay.

Frequently asked questions
Are these official NEET 2020 Physics Current Electricity PYQs?
No. The previews are original NeetVellum practice questions. A historical item receives a PYQ label only after its official paper and authoritative final answer key are attached. Use the official archive for the source paper.
How should I use the NEET 2020 paper?
Solve the official paper under its original timing, verify against the final key, classify every miss, and then use the linked current-syllabus practice bank to repair the exposed concept.
