A household appliance has a power rating of 800W and is used for 3 hours per day. How much energy does it consume in a week?
To calculate the energy, we multiply the daily energy consumption by the number of days in a week.
Daily energy consumption = 800W × 3h = 2400Wh
Weekly energy consumption = 2400Wh × 7 days = 16,800Wh or 16.8 kWh.
