NEET 2022 Physics Current Electricity Questions
Use this page to connect the official 2022 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 bulb connected by a long metallic wire begins to glow very soon after a switch is closed, even though electron drift speed is very small. What is the best explanation?
- A. Each electron instantly acquires a speed equal to the speed of light.
- B. The electrons already in the bulb travel to the switch before it closes.
- C. Drift speed becomes infinite for a short interval.
- D. The electric field is established through the circuit rapidly, setting nearby electrons into drift.
Example 3 · difficulty 3/5
A steady current flows through a tapered metallic conductor whose cross-sectional area decreases gradually along its length. Which statement is correct?
- A. The current is the same at all sections, but current density is greater where the area is smaller.
- B. Both current and current density are the same at all sections.
- C. Current is greater at the narrower section, but current density is unchanged.
- D. Current decreases toward the narrower section because fewer electrons can pass.
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 2022 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 2022 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.
