1. What is AC Power Consumption?

AC Power Consumption refers to the amount of electrical energy used by AC (alternating current) devices over a specific period. It is measured in kilowatt-hours (kWh) and is essential for understanding energy usage and costs.

2. How Does the Calculator Work?

The calculator uses the basic power consumption formula:

Where:

• \( E \) — Energy consumption (kWh)
• \( P \) — Power (kW)
• \( t \) — Time (hours)

Explanation: This simple formula calculates the total energy consumed by multiplying the power rating of the device by the duration of use.

3. Importance of Energy Calculation

Details: Calculating energy consumption helps in estimating electricity costs, managing energy usage, and making informed decisions about energy-efficient appliances.

4. Using the Calculator

Tips: Enter power in kilowatts (kW) and time in hours. Both values must be positive numbers. For devices rated in watts, convert to kW by dividing by 1000.

5. Frequently Asked Questions (FAQ)

Q1: How do I convert watts to kilowatts?
A: Divide the watt value by 1000. For example, 1500 watts = 1.5 kW.

Q2: Can I use this for DC power consumption?
A: While the formula is the same, this calculator is specifically designed for AC power consumption calculations.

Q3: What is a typical power consumption for household appliances?
A: It varies widely - refrigerators use 100-400W, TVs 50-200W, and air conditioners 1000-5000W.

Q4: How accurate is this calculation?
A: The calculation provides theoretical consumption. Actual consumption may vary based on device efficiency, power factors, and usage patterns.

Q5: Can I calculate energy costs with this?
A: Yes, multiply the result by your electricity rate (per kWh) to estimate costs.
