Question 33:
Two exactly similar heating resistances are connected (i) in series, and (ii) in parallel, in two different circuits, one by one. If the same current is passed through both the combinations, is more heat obtained per minute when they are connected in series or when they are connected in parallel ? Give reason for your answer.

More heat obtained when they are in series because of H = I² R t
I and t is same in both circuits and R is different.
Resistance is always maximum in series and always minimum in parallel. More resistance more heat. So, more heat obtained when resistances are connected in series.
