Is equal to ido.

If s is a specific charge that is charged by, carried by each charge carrier of the conductor and l is the length of the conductor, then the total force experienced by all the charge carriers for unit length of the conductor due to their drift velocity only is.

The vector of a length area a and length l.

Let the number of electrons per unit volume is let number of electrons per unit volume is equal to vd equals to n.
01:02
A number of electrons in volume al is a number of electrons in volume al is a number of electrons in volume a .l is equal to n a .r.

So, momentum, p can be written as p is equals to m, npd.
01:37
Trip velocity and current i is equals to n e, a, vd.
01:45
So from here, vd is equals to i divided by n -ea...
