Question

In the following circuits (Figure 12.2), the heat produced in the resistor or combination of resistors connected to a 12 V battery will be

(1 Point)

(a) same in all the cases

(b) minimum in case (i)

(c) maximum in case(ii)

(d) maximum in case(iii)

​

Answer 1

Explanation:

Heat is directly proportional to resistance

since, H=(I^2)RT

where H - heat, I - current, R - resistance, T - time

In series resistance is more as compared to the parallel.
