Question

Rajiv connected two exactly similar heating elements (or resistances) across a mains supply in two different ways to heat some water.
(a) Is more heat obtained when the heating elements are connected in series or when they are connected in parallel?
​(b) Give reasons for your answer.

Answer 1

Answer:

HEY MATE...

EXPLANATION:

Resultant resistance in a series combination is greater than any individual resistance, and resultant resistance in a parallel combination is smaller than any individual resistance.

Since His proportional to R; so more the resistance, more the heat. Therefore, the resistances must be connected in series to obtain more heat per minute.
