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...

b. Three electric bulbs are connected in circuit with the 120 V battery as shown in the circuit diagram below . With the switch open (a) The manufacturer specifications for the cach bulb are 120V, 40W; 120V, 20W and 120V, 60W respectively. Using this specifications (means apply a 120 V to calculate the resistance of the bulbs), calculate the resistance of each bulb, note that the resistance of the bulbs remain constant. (R-360...

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...
