Across a metallic conductor of non-uniform cross section a constant potential difference is applied. The quantity which remains constant along the conductor is:

  • Option 1)

    current

  • Option 2)

    drift velocity

  • Option 3)

    electric field

  • Option 4)

    current density

As learnt in

Ohm's Law -

Current flowing through the conductor is directly proportional to the Potential difference accross two ends .

- wherein

unit -   \frac{m^{2}}{volt\cdot sec}

 

V \alpha  I

V=IR

R- Electric Resistance

 

 Current remains constant, all other quantity depends on the cross sectional area.


Option 1)

current

This option is correct.
 

Option 2)

drift velocity

This option is incorrect.
 

Option 3)

electric field

This option is incorrect.
 

Option 4)

current density

This option is incorrect.
