To calculate the energy consumption in kilowatt-hours (kWh) for reheating a ceramic cup of coffee in a microwave for 1 minute, you need to know the microwave's wattage. Most microwaves have their power rating (wattage) specified on the back or inside the door.
Let's assume a typical microwave has a power rating of 1000 watts (1 kilowatt).
To calculate the energy consumption:
Convert the time from minutes to hours: 1 minute ÷ 60 minutes/hour = 0.01667 hours
Calculate the energy consumption in kilowatt-hours (kWh): Energy (kWh) = Power (kW) x Time (hours) Energy (kWh) = 1 kW x 0.01667 hours Energy (kWh) ≈ 0.01667 kWh
Reheating a ceramic cup of coffee in a typical microwave for 1 minute would add up to approximately 0.01667 kWh of energy consumption. Keep in mind that this is an estimation based on the assumption of a 1000-watt microwave and doesn't account for any additional energy used during standby mode or other factors.
