You are at least going to need to close the circuit at the upper left. The instructions don;t seem to be entirely clear on this problem, but again the first thing I would try is simply close the circuit at the upper left. And you need to write out the current and voltage equations. It takes a little work, but when you get tested on the material, they are not going to write the equations for you. That is what homeworks are for=to learn by trial and error. ## \\ ## One way to get them to shine equally bright is to simply put the bulbs next to each other in series in the circuit=they aren't real clear on what you are allowed to do to the circuit. ## \\ ## Edit: My suggestion of shorting the circuit at the upper left will not work. This one is actually kind of simple now that I have looked it over carefully, and it does not require extensive circuit analysis. If you look at the bulb at the lower left, it is in series circuit with the voltage source with resistances totaling ## R=2.3 \, k \Omega ## . How would you modify the circuit to get the same thing for the other bulb? That will give you the solution you need.
