When the current

i

is flowing a conductor, the drift velocity is

v

. If

2i

current is flowed through the same metal but having double the area of cross-section, then the drift velocity will be

View answer and explanation

Correct option: C

v

Option C (

v

) is correct because the drift velocity is proportional to the current density, and the current density remains the same when both current and area are doubled.
