Given that each individual resistor can dissipate up to 1 watt of power before burning up, how much total power in watts ( W ) can the smallest-valued composite resistor dissipate before burning up? 

P=V^2/Rmin_______(1)
P=1 Watt
Rmin=R1=R2=4 Ohms, and R3= 6 Ohms

Find V

In equation 1

1=V^2/4

V=2

Put V in equation 1

P=V^2/R3
P=(2)^2/6
P=2.667 W
