1. What is Power Consumption Calculation?

Definition: This calculator estimates the energy consumption in kilowatt-hours based on the power rating of an appliance and its usage time.

Purpose: It helps homeowners and businesses understand their electricity usage and estimate energy costs.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( E \) — Energy consumption (kilowatt-hours)
• \( P \) — Power rating (watts)
• \( t \) — Time of usage (hours)

Explanation: The power in watts is multiplied by time in hours, then divided by 1000 to convert to kilowatt-hours (kWh).

3. Importance of Power Consumption Calculation

Details: Understanding energy usage helps in budgeting electricity costs, comparing appliance efficiency, and reducing energy waste.

4. Using the Calculator

Tips: Enter the appliance's power rating in watts and the duration of use in hours. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Where can I find an appliance's power rating?
A: Check the manufacturer's label, specification sheet, or product manual. It's often listed in watts (W) or kilowatts (kW).

Q2: How do I calculate monthly energy consumption?
A: Multiply the daily kWh result by the number of days used per month.

Q3: How does this relate to my electricity bill?
A: Multiply the kWh result by your electricity rate (per kWh) to estimate cost.

Q4: What's the difference between watts and kilowatt-hours?
A: Watts measure power (rate of energy use), while kilowatt-hours measure energy consumption over time.

Q5: Can I use this for multiple appliances?
A: Yes, calculate each separately and sum the results for total consumption.
