Question

Two conducting wires of the same material and of equal length and equal diameters are first connected in series and in parallel in a circuit across the same potential difference . The ratio of heat produced in series and parallel combination would be..??​

Answer 1

Answer:

Correct option is

C

1:4

Since the two wires have same material, length and diameter, they have the same resistance. Let the resistance of each wire be R.

Let applied potential difference be V

Answer 2

Answer:

4:1

Explanation:

Resistance in series =R+R

Resistance in parallel = 1R + 1/R (inverse)
