Two light bulbs are connected in parallel, and then connected to
a battery, as shown in Fig. 4.51(a). You observe that bulb 1 is
twice as bright as bulb 2. Assuming that the brightness of a bulb
is proportional to the power dissipated in the bulb’s resistor,
which bulb’s resistor is larger, and by what factor? The bulbs are
now connected in series ,as shown in Fig.4.51(b). Which bulb is
brighter, and by what factor? How bright is each bulb...
