Chapter , Problem 64

(choose chapter or problem)

Consider the two arrangements of batteries and bulbsshown in Figure P18.64. The two bulbs are identicaland have resistance R, and the two batteries are identicalwith output voltage DV. (a) In case 1, with the twobulbs in series, compare the brightness of each bulb,the current in each bulb, and the power delivered toeach bulb. (b) In case 2, with the two bulbs in parallel,compare the brightness of each bulb, the currentin each bulb, and the power supplied to each bulb.(c) Which bulbs are brighter, those in case 1 or thosein case 2? (d) In each case, if one bulb fails, will theother go out as well? If the other bulb doesnt fail, willit get brighter or stay the same? ( is courtesyof E. F. Redish.
