Physics help...+K

I am having troubles with this physics problem. Id appreciate any help. I keep getting 11.24 volts, but thats not the right answer.

in the circuit shown in the figure

all the resistors are rated at a maximum power of 1.00 w

What is the maximum emf that the battery can have without burning up any of the resistors?

I am pretty sure the answer is 20V exactly... I put the circiut into a simulator, and cranked it untill a resistor went over 1W... the resistor which maxes out is the botomish far right.

If you need calculation help let me know. But knowing which resistor will peak first makes that part much easier.

thanks that was it. i understand what i was doing wrong
