You obtain a 100-W light bulb and a 50-W light bulb. Instead of connecting them in the normal way, you devise a circuit that places them in series across normal household voltage. Which statement is correct?
A)Both bulbs glow at the same reduced brightness.
B)Both bulbs glow at the same increased brightness.
C)The 100-W bulb glows more brightly than the 50-W bulb.
D)The 50-W bulb glows more brightly than the 100-W bulb.

When connected in series, the same current flows through both bulbs. The bulb with the higher resistance (50-W bulb) will have a higher voltage drop across it and will glow more brightly than the 100-W bulb.
