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

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

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 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 ?

The drift velocity of electrons in a wire of radius r is proportional to

Drift velocity of free electrons when current passes through the conductor is of the order of

When a current of 1 A flows through a copper wire of cross sectional area 1mm^2 the drift velocity of free electrons becomes v, What will be the drift velocity of free electrons when the same current flows through a copper wire of cross sectional area 2mm^2 ?

A current .I. flows through a metallic wire of radius .r. and the free electrons in it drift with a velocity v_(d) . Calculate the drift velocity of the free electrons through the wire of the same material, having double the radius, when same current flows through it.
