Question

find the ratio of resistance of two wires of same Satyawati and same length the diameter just double of second wire to first wire

Answer 1

ratio of resistance between the wire depend upon there diameter

ratio of diameter of first wire:ratio of diameter of second wire
ratio of resistance in first wire: ratio of resistance in second wire

1:2 is the ratio.


since length and PV are same so they are not taken in to consideration
