Question

Two conducting wires of same material, equal length and equal diameter are connected in series. How does the heat produced by combination of resistance change

Answer 1

Explanation:

As the 2 wires are of same material ,equal length & equal diameter their resistances are also equal.

2 resistances in series means the total net resistance is 2R.

Now heat which is produced is given by Joule's Law of heating as H=I2Rt.

So H is directly proportional to R. Therefore heat produced by the combination doubles as compared to a single resistance.

Answer 2

Answer:

Their resistance are also equal. therefore heat produced by the combination doubles as compared to a single resistance.
