Original practice preview

These are current-syllabus NeetVellum questions, shown separately from historical-paper provenance.

Example 1 · difficulty 2/5

The electric field in a metal is doubled while the electron relaxation time and all other relevant quantities remain unchanged. What happens to the electron drift velocity?

  • A. Its magnitude becomes half and its direction reverses.
  • B. Its magnitude remains unchanged.
  • C. Its magnitude doubles, while it remains opposite to the electric field.
  • D. Its magnitude becomes four times and it becomes parallel to the electric field.

Example 2 · difficulty 1/5

In the classical description of conduction in a metal, relaxation time is best described as the

  • A. time taken by an electron to cross the entire wire.
  • B. time for the electric field to become zero after connecting a cell.
  • C. period of circular motion of an electron inside the metal.
  • D. average time between two successive collisions of a conduction electron.

Example 3 · difficulty 2/5

A metal has free-electron number density 8.0 × 10²⁸ m⁻³. A wire of this metal has cross-sectional area 1.0 × 10⁻⁶ m², and the electron drift-speed magnitude is 2.0 × 10⁻⁴ m s⁻¹. Taking e = 1.6 × 10⁻¹⁹ C, find the current.

  • A. 2.56 A
  • B. 0.256 A
  • C. 25.6 A
  • D. 256 A

The evidence-first practice loop

  1. 1. Verify provenanceOfficial paper and final key before accepting a PYQ label.
  2. 2. Attempt closed-bookExpose the concept or execution gap before rereading.
  3. 3. Repair and returnClassify the miss and re-practice after a delay.

Frequently asked questions

Are these official NEET 2018 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 2018 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.
