1. What is the Energy Consumption Formula?

The energy consumption formula E = P × t calculates the total energy consumed by an electrical device, where E is energy in kilowatt-hours (kWh), P is power in kilowatts (kW), and t is time in hours.

2. How Does the Calculator Work?

The calculator uses the energy consumption formula:

Where:

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

Explanation: This simple formula multiplies the power rating of the AC unit by the operating time to determine total energy consumption.

3. Importance of Energy Calculation

Details: Calculating energy consumption helps estimate electricity costs, assess energy efficiency, and make informed decisions about AC usage patterns to reduce energy bills.

4. Using the Calculator

Tips: Enter the AC unit's power consumption in kW and the operating time in hours. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

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

Q2: What is a typical power consumption for an AC unit?
A: Residential AC units typically range from 1-5 kW, depending on size and efficiency rating.

Q3: How accurate is this calculation?
A: This provides a basic estimate. Actual consumption may vary based on temperature settings, outdoor conditions, and AC efficiency.

Q4: Can I use this for other electrical appliances?
A: Yes, the formula E = P × t works for any electrical device when you know its power consumption and operating time.

Q5: How can I reduce my AC energy consumption?
A: Use programmable thermostats, maintain proper insulation, clean filters regularly, and consider energy-efficient models.
