1. What is AC Power Consumption Calculator?

Definition: This calculator estimates the energy consumption of electrical devices based on their power rating and usage time.

Purpose: It helps users understand and estimate electricity usage for better energy management and cost calculation.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

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

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

3. Importance of Power Consumption Calculation

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

4. Using the Calculator

Tips: Enter the device's power rating in watts and the duration of use in hours. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Where can I find the power rating of my device?
A: Check the device's label, manual, or specifications sheet. It's usually listed in watts (W) or kilowatts (kW).

Q2: How accurate is this calculation?
A: It provides a basic estimate. Actual consumption may vary based on usage patterns, power fluctuations, and device efficiency.

Q3: Can I use this for DC devices?
A: Yes, the formula works for any electrical device as long as you have the correct power rating in watts.

Q4: How do I convert the result to cost?
A: Multiply the kWh result by your electricity rate (per kWh) to estimate cost.

Q5: Why divide by 1000?
A: This converts watt-hours to kilowatt-hours (1 kWh = 1000 Wh), which is the standard unit for electricity billing.
