velocitydrift=I/N*Area*chargeonelectron
I don't understand what it is that you don't understand. It is a simple formula. Convert current to amps, area to m^2, N to electcrons per cubic meter
Please help and do it step by step all parts of questions and use:
T = time(s)
I=current (amps)
Q=net charge on object (Coulombs)
N=no electrons (and write if added or removed from object and how)
E=elementary charge
A piece of fuse wire has a diameter of 0.22mm and carries a current of 5.0A. There are 1.0 x 10^29 electrons per metre cubed. Calculate the mean drift velocity of the electrons in the wire.
