1. What is Power Consumption?

Power consumption refers to the amount of electrical energy used by a device or system over 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:

Where:

• \( \text{Power (W)} \) — Electrical power in watts
• \( 1000 \) — Conversion factor from watts to kilowatts

Explanation: This formula converts power consumption from watts to kilowatt-hours per hour, providing the energy consumption rate.

3. Importance of Power Consumption Calculation

Details: Calculating power consumption is essential for energy management, cost estimation, environmental impact assessment, and electrical system design. It helps in understanding energy usage patterns and optimizing efficiency.

4. Using the Calculator

Tips: Enter the power rating in watts (W). The value must be greater than zero. The calculator will provide the consumption in kilowatt-hours per hour (kWh/hour).

5. Frequently Asked Questions (FAQ)

Q1: What is the difference between power and energy consumption?
A: Power (watts) is the rate of energy use, while energy consumption (kWh) is the total amount of energy used over time.

Q2: How do I calculate daily energy consumption?
A: Multiply the hourly consumption by the number of hours the device operates per day.

Q3: What is a typical power consumption for household appliances?
A: It varies widely - LED bulbs (5-15W), refrigerators (100-800W), air conditioners (1000-5000W).

Q4: Why convert watts to kilowatts?
A: Utility companies typically bill in kilowatt-hours, so conversion helps estimate electricity costs.

Q5: Does this calculation account for power factor?
A: No, this is a basic calculation assuming pure resistive load. For reactive loads, additional factors may need consideration.
