QUESTION In comparing wires of identical shape and carrying the same current but made of differentmetals, is the drift velocity in each wire inversely proportional to the number density of charge carriers?O Yes. To have the same current from k times as many carriers, it takes 1/k times the drift speed.Yes. To have the same current from k times as many carriers, it takes k times the drift speed.No. The drift velocity is directly proportional to the number density of carriers.No. The drift velocity is the same for all conductors.PRACTICE ITUse the worked example above to help you solve this problem.

Concept explainers

Microscopic view of current

In physics, the term current is expressed as the rate of flow of electric charges across the area per unit time (I=q/t). It propagates along in the direction of the motion of positive charges. When the current is caused by the motion of electrons, the direction of the current is opposite to the flow.
