Two different wires X and Y of same diameter but different materials are joined together in series across a battery . If the number density of electrons in X is twice that in Y . Find ratio of drift velocity of electrons in two wires .

Answer:
In series combination, the current is the same.
I = nAev
=> n1v1 = n2 v2
=> v1:v2 =n2:n1
