A straight conductor of uniform cross-section carries a current `I`. Let `s=` specific charge of an electron. The momentum of all the free electrons per unit length of the conductor, due to their drift velocity only, is

In a straight conductor of uniform cross-section charge q is flowing for time t. Let s be the specific charge of an electron. The momentum of all the free electrons per unit length of the conductor, due to their drift velocity only is

In a straight conductor of uniform cross-section charege q is flowing for time t. Let s be the specific charge of an electron. The momentum of all the free electrons per unit length of the free electrons per unit length of the conductor, due to their drift velocity only is

A conductor of uniform cross-section is carrying a current of a ampere. The number of free electrons flowing across the across the cross- section of the condukctor per second is

A conductor of uniform cross-section is carrying a current of 1 ampere. The number of free electrons flowing across the cross section of the conductor per second is

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

A straight conductor of uniform cross section carries a time varying current, which varies at the rate dI//dt = I. If s is the specific charge that is carried by each charge carries of the conductor and l is the length of the condcutor, then the totalt force experienced by all the charge carries per unit length of the conductor due to their drift velocities only is
