Question

Which of the following is the valid expansion for equivalent resistance's rp when rresistore r1 andr2 are connected in paralle

Answer 1

Answer:

Heat produced, H=RV2t 

both resistances are connected in parallel combination that's why both will get equal voltage drop hence heat produced will directly depend upon resitance value of them.

i.e. H∝R1

so H2H1=R1R2
