Question

The drift velocity of free electrons in a conductor is vd when current is flowing through it if both the radius and current are doubled and the dove velocity will be

Answer 1

Explanation:

Then the drift velocity is 1/ 4 time of the initial value .

Drift velocity is inversely proportional to radius of conductor.

Thank you

Answer 2

Explanation:

the drift velocity is v if 2i current is ... metal but having double the area of cross section then the drift velocity will be.
