Question

please tell the answer by explaining the reasons for this question
In the following circuits, heat produced in the resistor or combination of resistors connected to a 12 V battery will be

Answer 1

Answer:

option (c) is correct .....please mark as brainliest

Explanation:

H= I²RT

the resultant resistance in case(i) = 2 ohms

the resultant resistance in case(ii)= 2+2=4 ohms

the resultant resistance in case(iii) = 1 ohm

the voltage is constant in the three cases

I in case (i) = V/R

= 12/2= 6

I in case (ii) = V/R

= 12/4= 3

I in case (iii) = V/R

= 12/1 = 12

We know that heat H is directly proportional to I

so it is maximum for case (iii) and minimum for case (ii)

so option (3) is correct please mark as the brainliest
