Could you be more specific?

Kirchhoff's 2nd law has often been quite helpful for me - the sum of emfs supplied around each loop of a circuit is equal to the sum of potential differences across all components.

It's not a pleasant topic. What in particular is the problem?

So, volume = A*L , v=d/t and Q=IT
Total charge, Q=n*e*V so the amount of electrons n, with charge e, in a given volume V
so, Q=n*e*A*L
I=(n*e*A*L)/t and as speed=dist/time.
I=n*e*a*v and then v=I/nae
