Enter the actual mass and the theoretical mass into the calculator to determine the Current Efficiency.

## Current Efficiency Formula

The following formula is used to calculate the Current Efficiency.

Ec = AM / TM * 100

• Where Ec is the Current Efficiency (%)
• AM is the actual mass
• TM is the theoretical mass

## How to Calculate Current Efficiency?

The following two example problems outline how to calculate the Current Efficiency.

Example Problem #1:

1. First, determine the actual mass. In this example, the actual mass is given as 78.
2. Next, determine the theoretical mass. For this problem, the theoretical mass is given as 80.
3. Finally, calculate the Current Efficiency using the equation above:

Ec = AM / TM * 100

Inserting the values from above and solving the equation:

Ec = 78 / 80 * 100 = 97.5 (%)

Example Problem #2:

Using the same process as above, first define the variables required by the formula. In this case, these values are:

actual mass = 90

theoretical mass = 95

Entering these values yields:

Ec = AM / TM * 100 = 94.73 (%)
