I need help with this problem please
Three 100 resistors are connected as shown in Figure P18.12. The maximum power that can safely be delivered to any one resistor is 28.5 W.
_____/\/\/\___
a.______/\/\/\____| |_______b
|____/\/\/\___|

Figure P18.12
(a) What is the maximum voltage that can be applied to the terminals a and b?


(b) For the voltage determined in part (a), what is the power delivered to each resistor?

Your answer differs from the correct answer by orders of magnitude. W
resistor at top of loop
W
resistor at bottom of loop W

What is the total power delivered?
W

do you still need help with this? how exactly are they connected? i can't tell from the picture.. Are they in series or are they supposed to be paralell?

I cant tell If they are in series or parallel either. Although Ill try to help as much as I can. P=VI=V^2/R
So R in a series is the sum of the other resistors whereas in a paralell circuit 1/R=Sum(1/R1+1/R2 ...)
so with this information you should be able to determine the Voltage.
