Question

Two identical resistors, each of resistance 15 , are connected in
(1) 06:
5
(1) series, and (ii) parallel, in turn to a battery of 6 V. Calculate the ratio
245
of the power consumed in the combination of resistors in each case.​

Answer 1

Answer:

1:4

Explanation:

total resistance in parallel = 1/15 + 1/15

which will become 7.5

power in parallel = v²/R == 6²/7.5

tatal resistance in series =15+15 =30

Power in series = V ²/R==6²/30

power in parallel/power in series = 30/7.5

which is 1/4

therefore Ratio = 1:4
