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...

The three light bulbs in the circuit all have the same resistance. Given that brightness is proportional to power dissipated, the brightness of bulbs B and C together, compared with the brightness of bulb A, is Twice as much, the same, half as much? The light bulbs in the circuit are identical. When the switch is closed, 12 V 12 VF Both lamps go out The intensity of light bulb...

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...
