Two metallic wires of the same material B, have the same length out cross-sectional area is in the ratio 1:2. They are connected (i) in series and (ii) in parallel. Compare the drift velocities of electrons in the two wires in both the cases (i) and (ii) .

Two metallic wires P_(1) & P_(2) of the same material & same length but different cross sectional areas A_(1) & A_(2) are joined together & connected to a source of emf. Find the ratio of the drift velocities of free electrons in the two wires when they are connected in parallel.
