1. What is Power Consumption?

Power consumption refers to the amount of electrical energy used by a device or appliance over a specific period of time. It is typically measured in kilowatt-hours (kWh), which represents the energy consumption of a 1000-watt device running for one hour.

2. How Does the Calculator Work?

The calculator uses the power consumption formula:

\[ kWh = \frac{Watts \times Hours}{1000} \]

Where:

\( Watts \) — Power rating of the device in watts
\( Hours \) — Duration of usage in hours
\( 1000 \) — Conversion factor from watts to kilowatts
\( kWh \) — Energy consumption in kilowatt-hours

Explanation: This formula converts the power consumption from watts to kilowatts and multiplies by the time in hours to calculate total energy usage.

3. Importance of Power Consumption Calculation

Details: Calculating power consumption helps in understanding energy usage patterns, estimating electricity costs, identifying energy-efficient appliances, and managing energy consumption for cost savings and environmental sustainability.

4. Using the Calculator

Tips: Enter the wattage of your device and the number of hours it operates. Both values must be positive numbers. The calculator will provide the energy consumption in kilowatt-hours.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between watts and kilowatt-hours?
A: Watts measure power (rate of energy use), while kilowatt-hours measure energy consumption (power × time).

Q2: How do I find the wattage of my appliance?
A: Check the manufacturer's label, specification sheet, or user manual. Most appliances have wattage information printed on them.

Q3: Can I calculate monthly electricity cost with this?
A: Yes, multiply the kWh result by your electricity rate (cost per kWh) and by the number of days used per month.

Q4: What is a typical power consumption for household appliances?
A: LED bulbs: 5-15W, Laptop: 50-100W, Refrigerator: 100-400W, Air conditioner: 1000-5000W.

Q5: Why divide by 1000 in the formula?
A: To convert from watts to kilowatts (1 kilowatt = 1000 watts), since electricity is typically billed in kilowatt-hours.
