Understanding Appliance Wattage
How Electricity Consumption Works
Your electricity bill is based on kilowatt-hours (kWh), which represents the amount of energy consumed over time. The formula for calculating energy consumption is:
Energy (kWh) = (Power × Hours × Quantity) ÷ 1000
Key Factors
- •Wattage: Power rating of the appliance
- •Usage hours: How long the appliance runs per day
- •Quantity: Number of similar appliances
- •Unit cost: Price per kWh on your electricity bill
Reading Appliance Labels
The wattage rating is usually found on a label on the back or bottom of appliances. Look for terms like "Watts", "W", or "Power Rating".
Typical Power Consumption
Note: Actual consumption may vary based on appliance age, efficiency rating, and usage patterns.
