1. What is Cost Per Second?

The Cost Per Second (CPS) calculation helps determine the electricity cost for devices running for very short durations. It's particularly useful for understanding the cost implications of frequently switching devices on and off.

2. How Does the Calculator Work?

The calculator uses the CPS formula:

Where:

• \( Power \) — Power consumption in kilowatts (kW)
• \( Rate \) — Electricity rate in currency per kilowatt-hour
• \( Time \) — Duration in seconds

Explanation: The equation calculates the cost of running an electrical device for one second based on its power consumption and your electricity rate.

3. Importance of CPS Calculation

Details: Understanding cost per second helps in making informed decisions about energy usage, especially for devices that cycle frequently or operate for short durations.

4. Using the Calculator

Tips: Enter power in kW, rate in your local currency per kWh, and time in seconds. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Why calculate cost per second instead of per hour?
A: For devices that operate for very short durations, per-second costing provides more precise cost estimation.

Q2: How accurate is this calculation?
A: It provides a theoretical estimate. Actual costs may vary based on power factor, voltage fluctuations, and other factors.

Q3: Can I use this for multiple devices?
A: Yes, but you'll need to calculate each device separately or sum their power consumption if they run simultaneously.

Q4: Does this account for standby power?
A: No, this calculates only active power consumption. For complete analysis, include standby power measurements.

Q5: How can I reduce my CPS?
A: Use more energy-efficient devices, negotiate better electricity rates, or reduce usage during peak rate periods.
