WebHere V is constant (220V) I=V/P (ohm's law) P= (V^2)/R. (so far the same as @Prithvi Sriram mentioned, but here's the shortcut) if v is constant v^2 will also be constant. P is inversely proportional to R. if P increases, R decreases. that is why the 2nd bulb offers more resistance. remember---only if V is constant. WebAnswer is A. Nichrome is an ideal material, because it has relatively high resistance and forms an adherent layer of chromium oxide when it is heated for the first time. Material …
