The drift velocity of an electron in a wire varies
A)directly with the number of charge carriers per unit volume.
B)directly with the cross-sectional area of the conducting wire.
C)directly with the charge carried by it.
D)directly with the current flowing in the conducting wire.
E)inversely with the current flowing in the conducting wire.

Question

Quizplus · Accepted Answer

The drift velocity of an electron in a wire is directly proportional to the current flowing in the conducting wire. This is because the greater the current, the greater the electric field, and hence the greater the force acting on the electron, causing it to move faster. The other options are not directly related to the drift velocity of an electron in a wire.
