an electric heater takes current of 4 amp from a 250V supply when operating normally, how much time is taken by the heater to convert 400000 J of electrical energy?

Question

deepak · Answer

power = energy per unit time also, we know that power = I 2 R =IV hence power given out by the circuit= 4 x 250 =1000 J/s let the time taken to accumulate the required energy of 4,00,000J be t then, by the formula power = energy / time => t= 400000/1000 = 400 seconds hope this was helpful ;”)
