(a) What is the resistance of ten 100-W light bulbs connected in parallel? (b) in series? The resistance of a 100-W, 120-V light bulb is 144 Ohms.
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...

5. Are light bulbs brighter when they're connected in series or in parallel? 6. Consider a whole circuit. When the power supply is set to 12V, does the power supply provide more current to the whole circuit when it consists of 3 light bulbs connected in parallel or 3 light bulbs connected in series?
a.When two resistors RA and RB are combined in series and connected to a battery it is observed that the ratio of the power dissipated in RA to that dissipated in RB is equal to 10. If this arrangement is dismantled and the same two resistors connected in parallel to the same battery, what is the ratio of the power dissipated in RA to that dissipated in RB in this new circuit? b.How much energy is converted by a 12...
