NCERT Question 17 An electric heater of resistance 8 β¦ draws 15 A from the service mains 2 hours. Calculate the rate at which heat is developed in the heater. Given Resistance = R = 8 Ξ© Current = I = 15 A Time = t = 2 hours We know that, Rate at which heat is developed = πΈπππππ¦/ππππ = Power Now, Power = I2 R = (15)2 (8) = 225 Γ 8 = 1800 W Rate of change of heat is 1800 W Note: This answer does not match the end of the book answer.
