Two conducting wi A. 1 : 2
B. 2 : 1
C. 1 : 4
D. 4 : 1
Suppose the resistance of each one of the two wires is R.
Case (i) When both wires are connected in series. Then, net resistance will be R+
R = 2R.
Then, heat produced will be ( As H = I2 X R X T)
Case (ii) When both wires are connected in parallel. Then, net resistance will be
According to Ohms Law:
Then, heat produced will be
Now, The ratio after simplifying will be as follow:-
Thus, option (c) is correct.
