Explanation / Answer

Here ,

for the 10 Ohm resistors

maximum current is I

4.1 = I^2 * R

I = 0.64 A

Now, when 3 resistances are connected in parallel with each dissipating 4.1 W

total dissipation is more than 11 W , for making it equal to 10 Ohm

we need 4 resistors

hence ,the minimum number is 4
