heater problem....

Expert Answer:

heat produced by the wire is H= i2Rt

here "i" is the current in the wire , "R" is the resistance of the wire and "t" is the time for which current is flowing in the wire

now resistance is proportnal to the  length of the wire

so heat produced by the wire 1 is H1=i2Rt

and heat produced by the wire 2 is H2=i22Rt

then (H1/H2)=1:2
