Direct-Current Circuits 101 20. Even if the fuse were to burn out or the circuit breaker to trip, there would still be a current path through the device, and it would not be protected. 22. When connected in series, all bulbs carry the same current. Thus, the one with the lowest resistance dissipates the least power 2 IR = P and glows the dimmest. This is seen to be

Unformatted text preview: the bulb that is labeled “200 W”. If they were connected in parallel, all bulbs would have the same potential difference across them. Then, the one with the lowest resistance will dissipate the most power ( ) 2 V = ∆ P R and glow the brightest. 24. The break is closer to A....
