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`?

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

The current i flows in a wire of circular cross-section with the free electrons travelling with a drift velocity v. What is the drift velocity of electrons when a current of 2 i flows in another wire of twice the radius and of the same material ?

A current flows in a wire of circular cross section with the free electrons travelling with drift velocity vecV . If an equal current flows in a wire of twice the radius, new drift velocity is

The drift velocity of free electrons in a conductor is v, when a current i is flowing in it, Ifboth the radius and current are doubled, then the drift velocity will be :

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
