Consider a conductor of length 0.5 m. A potential difference of 20V is applied across this conductor. If the drift velocity of electrons is given as 5.0 × 10-4ms-1, then determine the mobility of the electrons.

The drift velocity of electrons for a conductor connected in an electrical circuit is Vd. The conductor in now replaced by another conductor with same material and same length but double the area of cross section. The applied voltage remains same. The new drift velocity of electrons will be

here is a current of 20 amperes in a copper wire of square metre area of cross-section. If the number of free electrons per cubic metre is then the drift velocity is:

How does the drift velocity change with a change in the potentialdifference across the conductor?

conductor of copper, the density of free electons is 5×10^23 electrons per unit volume, carrying current of intenisty 1.6A if the cross-sectional area of a conductor is 4mm^2 so the drift velocity of electrons is
