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...

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...

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 Investigation #11: Non-Identical Bulbs in Series and Parallel All of the circuits you have investigated so far have involved identical bulbs. If two bulbs are identical and one bulb is brighter, then the brighter bulb must have a larger current thru it. Furthermore, the larger current must be caused by a larger potential difference. In this investigation, you will study circuits for which the bulbs are not identical. We will illustrate that two Spherical bulbs are not identical by...

A set of four "80 - year," fifty (50) watt light bulbs
costs $24.29. If H equals the annual number of hours the bulb is
used, each bulb provides 80H hours of light, and the efficiency of
each bulb is 75%. A set of four, fifty(50) watt standard bulbs
costs $2.31. Each standard bulb provides H hours of light and the
efficiency of each bulb is 90%. If the cost of electricity is
$0.0582/kWh, how many hours of operation each...
