  In the following circuits, heat produced in the resistor or combination of resistors connected to a 12 V battery will. be (a) same in all the cases                                                (b) maximum in case (i) (c) maximum in case (ii)                                                (d) maximum in case (iii)

Answer:

                  (d)in Case(i), Case(ii), Case (iii), Since, ,As voltage in the three cases for equivalent resistance is same so,  So heat produced is maximum in case (iii).
