Question

conducting wires of the same material and of equal lengths and equal diameters are first connected in series and then in parallel in an electric circuit across the same potential difference the ratio of heat produced in series and parallel combination would be a =1 is to 2 ,b =2 is to 1, C =1 is 24 and d= 4 is to 1
​

Answer 1

Answer:

d) 4:1

Explanation:

h=i^2rt(formula)

h1=I^2*2rt

h2=i^2*rt/2

h1/h2=4:1
