Unformatted text preview: +-B A More light If the bulbs and the batteries in the circuits are identical, which circuit puts out more light? +-Circuit 2 Circuit 1 A. Circuit 1. B. Circuit 2. C. The two circuits emit the same amount of light. Three bulbs The three bulbs in the circuit below all have the same resistance. Given that brightness is proportional to dissipated power, the brightness of bulbs B and C together , compared with the brightness of bulb A, is A. twice as much. B. the same. C. half as much. +-B C A...

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
