1. What is the Energy Consumed Equation?

The Energy Consumed equation calculates the total energy consumption based on power usage over time. It provides a fundamental calculation for determining electricity consumption in various applications.

2. How Does the Calculator Work?

The calculator uses the Energy Consumed equation:

Where:

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

Explanation: The equation multiplies power consumption by time to determine total energy usage.

3. Importance of Energy Calculation

Details: Accurate energy calculation is crucial for electricity billing, energy efficiency analysis, environmental impact assessment, and electrical system design.

4. Using the Calculator

Tips: Enter power in kilowatts (kW) and time in hours. All values must be valid (power > 0, time > 0).

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between kW and kWh?
A: kW (kilowatt) measures power (rate of energy use), while kWh (kilowatt-hour) measures energy (total consumption over time).

Q2: How do I convert watts to kilowatts?
A: Divide watt value by 1000 (1 kW = 1000 W).

Q3: Can I use this for DC circuits?
A: Yes, the formula works for both AC and DC electrical systems.

Q4: What about power factor in AC circuits?
A: This calculator uses apparent power. For precise AC calculations, consider power factor correction.

Q5: How accurate is this calculation for billing purposes?
A: This provides an estimate. Actual billing may include additional factors like demand charges, time-of-use rates, and taxes.
