What Is Power?
Power is how quickly energy is used or work is done. Think of it like how fast water flows through a pipe - more power means more energy flowing per second. This is why some appliances use more electricity than others, and why some cars can accelerate faster than others. Power tells us the rate at which energy is being used.
Common Power Units
- Watts (W): Standard international unit (basic measurement)
- Kilowatts (kW): 1,000 watts (used for larger appliances)
- Horsepower (hp): Used for engines and motors
- Megawatts (MW): 1,000,000 watts (power plants)
When to Use Power Conversion
- Appliance Shopping: Compare power ratings of devices
- Electric Bills: Understand kilowatt-hour usage
- Car Shopping: Compare engine horsepower
- Solar Panels: Calculate power generation
- DIY Projects: Choose right motors and tools
Everyday Power Examples
- LED Light Bulb: 10 watts (very efficient lighting)
- Laptop Computer: 50-100 watts (moderate power use)
- Microwave Oven: 1,000 watts (1 kilowatt)
- Car Engine: 100-300 horsepower (75-225 kW)
- Power Plant: 500,000+ kilowatts (500+ megawatts)
Home Appliance Power Examples
- Phone Charger: 5-20 watts (charging devices)
- TV: 50-200 watts (depending on size and type)
- Refrigerator: 150-400 watts (running continuously)
- Air Conditioner: 1,000-5,000 watts (cooling power)
- Electric Oven: 2,000-5,000 watts (cooking)
Understanding Electricity Bills
- Kilowatt-hour (kWh): Energy used over time
- Example: 1,000-watt appliance running for 1 hour = 1 kWh
- Average Home: 30 kWh per day (varies by location)
- Cost: Usually $0.10-$0.20 per kWh
