Question

In the following given circuits, heat produced in the resistor orcombination of resistors connected to a 12 V battery will be

• A. same in all the cases.
• B. minimum in case (i).
• C. maximum in case (ii).
• D. maximum in case (iii).

Answer 1

Answer: (D)

maximum in case (iii).

Power is inversely proportional to resistance. And resistance is minimum in fig. III , hence heat will produced most in III.
