Heating Effect of Electric Current: When an electric current passes through the filaments of the bulb, it … WebApr 5, 2024 · The electrical resistance of the conductor. Higher the resistance, the higher the heat produced. The amount of current. The larger the amount of current the higher the heat produced. If the present is little then the quantity of warmth generated is probably going to be very small and should not be noticed.
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. WebH=I 2Rt. H=1 2×12×60. H=720J. (c) The heat produced by the heater will become one - fourth because heat produced is directly proportional to the square of the current. (d) …
