What is the Power Efficiency Calculator?

The Power Efficiency Calculator is a practical tool for engineers, students, and electronics enthusiasts to quickly determine the efficiency of a device or system. By entering the input power supplied to the device and the output power delivered, the calculator computes the efficiency as a percentage using the formula η = (Pout / Pin) × 100. This helps users understand how effectively a device converts input energy into useful output energy, making it easier to evaluate performance, reduce energy losses, and optimize electrical systems.

How to Use:

1. Enter Input Power (Pin): Input the power supplied to the device in watts (W).
2. Enter Output Power (Pout): Input the power delivered by the device in watts (W).
3. Click “Calculate”: The calculator computes the efficiency based on the entered values.
4. Review Result: The output displays the efficiency in percentage (%), shows all input values, and presents the formula used, helping you understand the proportion of input power converted into useful output.
