Current Efficiency Calculator

What is Current Efficiency?

Current efficiency is a measure of how effectively an electrical circuit or device converts input current to useful output current. It's expressed as a percentage and is calculated as the ratio of actual current to theoretical current capacity.

How to Use This Calculator

1. Enter the Actual Current (I_actual) flowing through your circuit in Amperes (A)
2. Enter the Theoretical Current (I_theoretical) - the maximum possible current your circuit could handle under ideal conditions, in Amperes (A)
3. Click the Calculate button to compute the current efficiency
4. The result will be displayed as a percentage (%)

Applications of Current Efficiency

Current efficiency is particularly important in:

• Electrolysis processes
• Battery performance analysis
• Rectifier efficiency calculations
• Conductor capacity assessments
• Power transmission system evaluations

Example

If a circuit has an actual current of 15A and a theoretical current capacity of 25A, the current efficiency would be:

η = (15A / 25A) × 100% = 60%

Note: Current efficiency below 100% indicates energy losses in the system, which could be due to resistance, heat, or other inefficiencies.
