Answer Key / Explanation : (c) -

(c)

Let resistors  have equal resistance

Let  be the total current then the current in resistor  and in resistor  are I/2.

So, heat produced in resistor  is

and heat produced in resistor  is

and heat produced in resistor  is

Hence, it is clear that the heat produced will be maximum in
