Question

In the following circuits (fig. 12.2), heat produced in the resistor or combination of resistors connected to a 12V battery will be:
(a) same in all cases
(b) minimum in case (i)
(c) maximum in case (ii)
(d) maximum in case (iii)​

Answer 1

Answer:

option c

Explanation:

amt of heat produced is directly proportional to the resistance.

so higher the resistance higher is the heat

Answer 2

Answer:

d)maximum in case(iii)
