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

    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?

  • Physics -

    A1/A2=1/6
    H = I2RT
    H=V2T/R
    R=PL/A
    H1/H2=1/6
