Two light bulbs are identical in every way, except Bulb A is glowing at 100% of its potential, while Bulb B is glowing at 50% of its potential. Which of the following statements are correct? (choose all that apply):
|
If Bulb B is close enough, it might appear brighter than Bulb A to our eyes. |
||
|
No matter how close Bulb A or Bulb B is to us, Bulb B will never appear as bright as Bulb A to our eyes. |
||
|
The bulb brightness that our eyes perceive depends on how bright the bulb is glowing, and its distance from us. |
||
|
The bulb brightness that our eyes perceive depends solely on how bright the bulb is glowing. |
||
|
The brightness of Bulb A and Bulb B that our eyes perceive depends solely on their distance. |
||
|
Bulb A will always appear brighter to our eyes. |
Homework Answers
The correct option is (c). The human eye perception depends on both the factors that how intense the object is and its distance from the eye.

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...

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...

has resistance 6 ohms. The battery has essentially no internal
resistance, and all the wires are essentially resistanceless,

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
