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 … WebApr 6, 2024 · The same current flowing through the tungsten filament of an electric bulb produces enormous heat but almost negligible heat is produced in the connecting wires of copper. This is because the fine tungsten filament has very high resistance whereas copper connecting wires have very low resistance. 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. north of brooklyn pizza toronto geary
