Appliance Power Calculator
Calculate power consumption, current draw, and energy costs for household appliances and electrical devices. Analyze energy usage patterns and operating costs.
Appliance Power Analysis
Apparent Power (VA)
S = V × I
Real Power (W)
P = V × I × cos φ
Reactive Power (VAR)
Q = V × I × sin φ
About Appliance Power Calculation
Understanding appliance power consumption helps optimize energy usage, calculate operating costs, and make informed decisions about energy efficiency.
Power Types:
- Real Power (W): Actual power consumed by the appliance
- Apparent Power (VA): Total power drawn from the supply
- Reactive Power (VAR): Power used by magnetic fields
- Power Factor: Ratio of real to apparent power
Typical Power Ratings:
- LED Bulb: 8-15W
- Laptop: 50-100W
- Refrigerator: 150-400W
- Microwave: 700-1200W
- Air Conditioner: 1000-3000W
