In a wire the current is I and the drift velocity of electrons is V.If radius is doubled then new current is

Electric current is due to drift of electrons in

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

A conductor is moving with the velocity v in the magnetic field and induced current is I. If the velocity of conductor becomes double, the induced current will be

If the current flowing in a copper wire be allowed to flow in another copper wire of same length but of doubled the radius, then what will be the effect on the drift velocity of the electrons. If the same current be allowed to flow in an iron wire of the same thickness, then ?

If the current flowing in a copper wire be allowed to flow in another copper wire of double the radius, then what will be the effect on the drift velocity of the electrons? If the same current be allowed to flow in an iron wire of the same thickness, then?

The ratio of electron and hole currents in a semiconductor is 7/4 and the ratio of drift velocities of electrons and holes is 5/4, then the ratio of concentrations of electrons and holes will be

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?

If A is the area of cross section of conductor, v_(d) is the drift velocity of electrons and n is the number of electrons per unit volume, then current density through conductor is

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 ?

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