Question

Two different light bulbs, labeled A and B, with filaments of the same material, are connected in series to a 6 V battery. The filament in bulb A is longer than filament B.
a. Which bulb glows brighter?
b. Which bulb has the greater current through it?
c. Which bulb has the greater potential difference between its terminals?
d. Which bulb has the greater resistance?

Answer 1

The current is the same in both as the are in series. The one with the longer filament (A) has the highest resistance, so it has the largest voltage across it, and the most power of the two, and therefore the brightest.

b both the same

c A

d A
