Question

Two conducting wires of the same material and of equal lengths and equal
diameters are first connected in series and then parallel in a circuit across the same
potential difference. The ratio of heat produced in series and parallel combinations
would be - (a) 1:2 (b) 2:1 (c) 1:4 (d) 4:1
​

Answer 1

Answer:

As the material, length and diameters of the two wires are the same hence, resistance would also be same in both the wires.
