Question

Two metallic wires of the same material have the same length but cross-sectinal area is in the ratio of 1:2.they are connected in
1)-series
2)-parallel.
Compare the drift velocities of the electrons in the two wires in both the cases.
Plzz help
series - 2:1
parallel - 1:1
Two wires A and B of the same material and having same length, have their
cross sectional areas in the ratio 1:6. What would be the ratio of heat produced
in these wires when same voltage is applied across each?
A1/A2=1/6
H = I2RT
H=V2T/R
R=PL/A
H1/H2=1/6
