The power that a lamp produces is
P = V^2/R
Since both lamp blubs are made to operate at the same voltage V, the lamp with more power must have a lower value of R. In this case,the 100W bulb has 1/4 the resistance of the 25W bulb.
This question makes no sense to me. . .
A 100-watt lamp glows brighter than a 25-watt lamp. What do you know about the resistances of these two lamps?
????
That they have different watts...thats all I can think of. Physics is not my strong subject.
