A 12-volt battery is connected to two light bulbs, as drawn in
Figure 1. Light bulb 1 has resistance 3 ohms, while light bulb 2
has resistance 6 ohms. The battery has essentially no internal
resistance, and all the wires are essentially resistanceless,
too.
When a light bulb is unscrewed, no current flows through that
branch of the circuit. For instance, if light bulb 2 is unscrewed,
current flows only around the lower loop of the circuit, which
consists of...

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...

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...
