Question
Two wires of identical radius of cross-section rrr, but
made of different materials, are joined end-to-end (i.e., in series). If the number density of free electrons (charge carriers) in the two wires is in the ratio 2:5, what will be the ratio of the drift velocities of electrons in the two wires?Solution
When two wires are connected in series , the current I flowing through both wires is the same . From the relation of current and drift velocity:
