The electric kettle marked with 220 V and 2000 W works normally for three minutes. How much electricity does it consume I don't know how to calculate the degree
This problem has nothing to do with the voltage of 220 v. there is such a formula that a kilowatt hour is equal to 1000 watts. That is to say, 1000 consumers consume one kilowatt hour. Now three minutes is 0.05 hours, so a 2000 Watt consumer consumes 0.1 kilowatt hour in three minutes
