Expert Answer
Resultant resistance in a series combination is greater than any individual resistance. Whereas the resultant resistance in a parallel combination is smaller than any individual resistance.
 
Since H  R; so more the resistance more will be the heat. Therefore, the resistances must be connected in series to the main supply to obtain more heat per minute.
