The electricity consumption of an electric kettle depends on its power rating and the duration for which it is used. Electric kettles typically have their power rating specified in watts (W). To calculate the units of electricity used, you can follow these steps:
Check the power rating of your electric kettle. It is usually mentioned on the label or in the user manual. Let's say the power rating is 1500 watts (W).
Convert the power rating to kilowatts (kW) by dividing by 1000: 1500 W ÷ 1000 = 1.5 kW
Determine the duration for which the kettle is used. Let's assume it's used for 10 minutes, which is 0.167 hours (10 minutes ÷ 60 minutes per hour).
Calculate the total electricity consumption in kilowatt-hours (kWh) using the formula: Electricity consumed (kWh) = Power rating (kW) × Time used (hours) Electricity consumed (kWh) = 1.5 kW × 0.167 hours ≈ 0.2515 kWh
So, using an electric kettle rated at 1500 watts for 10 minutes would consume approximately 0.2515 kilowatt-hours of electricity. Keep in mind that the power rating and usage time may vary for different electric kettles, so it's essential to check the specific details of your kettle for a more accurate estimation.
