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.
