The formula to calculate the cell potential (Ec) is:
\[ E_{c} = E_{ca} - E_{a} \]
Where:
Cell potential is defined as the difference between the cathode potential and the anode potential in a battery cell.
Let's assume the following values:
Using the formula to calculate the cell potential:
\[ E_{c} = 1.5 - 0.5 = 1.0 \text{ V} \]
The Cell Potential (Ec) is 1.0 V.
