A current `I` flows through a uniform wire of diameter `d` when the mean electron drift velocity is `v`. The same current will flow though a wire of diameter `d//2` made of the same material if the mean drift velocity of the electron is

Current I is flowing through a copper wire of radius r with drift velocity of electorns v_(d) . If this current is passed through another copper wire of same length and double the raduis, what will be the drift velocity of free electrons in it?

When a current I is set up in a wire of radius r, the drift velocity is v_(d) . If the same current is set up through a wire of radius 2r, the drift speed will be

When a current "i" flows through a wire,the drift velocity of electrons is "v_(d)" .When current "2" i flow through the another wire of same material having double length and same area of cross section and temperature,the drift velocity of the elections will be

When current flows through a conductor, then the order of drift velocity of electrons will be

Will current flow more easily through a thick wire or a thin wire of the same material when connected to the same source ? Why ?

A current i is flowing through the wire of diameter (d) having drift velocity of electrons v_(d) in it. What will be new drift velocity when diameter of wire is made d//4 ?

Two wires of the same material but of different diameters carry the same current i . If the ratio of their diameters is 2:1 , then the corresponding ratio of their mean drift velocities will be

In a wire of cross-section radius r , free electrons travel with drift velocity v when a current I flows through the wire. What is the current in another wire of half the radius and of the same material when the drift velocity is 2v ?
