Final answer:
The average power consumption of an appliance that uses 3.45 kWh of energy per day is 143.75 watts, calculated by dividing the energy consumed (in kilowatt-hours) by the total number of hours in a day.
Step-by-step explanation:
The average power consumption in watts of an appliance that uses 3.45 kWh of energy per day can be calculated by dividing the total energy used by the number of hours in a day. Since one day has 24 hours, you calculate the average power consumption by using the following formula: Average Power (W) = (Total Energy used in kWh × 1000) / Number of hours in a day.
In this case, with 3.45 kWh of energy use per day, the calculation would be: Average Power (W) = (3.45 kWh × 1000) / 24 = 143.75 watts.
The average power consumption of an appliance can be calculated by dividing the energy used by the time it takes to use that energy. In this case, the appliance uses 3.45 kW · h of energy per day. To convert this to watts, we multiply by 1000 to get 3450 watts. So, the average power consumption of the appliance is 3450 watts or 3.45 kilowatts.
