relative brightness

[Empire]

There are five light bulbs. Light bulb C and D are in a series connection. C and D are in a parallel connection with E. Light Bulb A and B are in a parallel connection. The two parallel connections are wired in a series connection. What would be their relative brightness? I'm thinking that A=B=E=C+D

First you have to make at least one assumption. I would assume that the light bulbs are identical, and that "brightness" means "total power emited". Then brightness ~ I2.

I disagree with your result (assuming I did it correctly). You need to use the voltage and current divider to examine this circuit.
