Current Electricity question

2015 · Q117

NEETPhysicsCurrent ElectricityMCQ+4 / −1
Across a metallic conductor of non-uniform cross section a constant potential difference is applied. The quantity which remains constant along the conductor is
  1. A
    drift velocity
  2. B
    electric field
  3. C
    current density
  4. D
    current
View written solutionFree

Correct answer: D

The area of cross section of conductor is non uniform so current density will be different but the flow of electrons will be uniform so current will be constant.
