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....

You obtain a 50-and a 100-W light bulb. Instead of connecting them in the normal way, you devise a circuit that places them in series across normal household voltage. If each one is an incandescent bulb of fixed resistance, which statement about these bulbs is correct? Both bulbs glow with the same brightness, but more than their normal brightness. The 100-W bulb glows brighter than the 50-W bulb. The 50-W bulb glows more brightly than the 100-W bulb, Both bulbs...

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...
