current efficiency calculator
Calculate electroplating or electrochemical process efficiency using = Actual Mass/Theoretical Mass×100
electrochemical current efficiency
Current efficiency is a measure of efficiency in the usage of an electrical current. It is given by dividing the actual output by the theoretical output and multiplying by 100 percent.
Formula & Table Summary:
\( \eta_{\%} = \frac{m_{\text{actual}}}{m_{\text{theoretical}}} \times 100 \)
Where: \( m_{\text{actual}} \) = actual mass, \( m_{\text{theoretical}} \) = theoretical mass
electroplating efficiency formula
A Current Efficiency Calculator calculates the efficiency of the utilization of electrical current used in electroplating, battery charging, or any other electrochemical process. It writes the mass of material deposited or energy stored to the theoretical mass which would be deposited or stored according to Faraday's law of electrolysis. This efficiency is as a percentage and reflects the proportion of electrical current provided that is actually employed useful manner in the desired reaction, with the remainder in side reactions, heating up, or other losses. In electroplating, as an example, the theoretical mass of metal plated out can be calculated by use of current, time, and the electrochemical equivalent of the material in question. In case the true mass is less than the actual mass, the current efficiency will be less than 100%. The fact that we are able to achieve high current efficiency implies that there is minimal waste and greater control over the process, which is highly necessary in industrial plating, energy storage, and chemical manufacturing processes.
battery charging current efficiency
| Actual Mass (g) | Theoretical Mass (g) | Calculation | Efficiency (%) |
|---|---|---|---|
| 1.8 | 2.0 | (1.8 / 2.0) × 100 | 90.0 |
| 5.0 | 5.2 | (5.0 / 5.2) × 100 | 96.15 |
| 10.5 | 12.0 | (10.5 / 12.0) × 100 | 87.5 |
| 0.95 | 1.00 | (0.95 / 1.00) × 100 | 95.0 |
| 3.2 | 3.5 | (3.2 / 3.5) × 100 | 91.43 |
