Question

Of the two bulbs, one glows brighter than the other. Which bulb has a higher resistance?

(a) Brightness is independent of resistance

(b) The bright bulb.

(c) Both have the same resistance

(d) The dim bulb

Answer 1

(d) The dim bulb

If the bulb is brighter, then it has more power and therefore has less resistance. On the other hand, if the bulb is dim, then it has less power. Therefore, the dim bulb has a large resistance.
