What is activation overpotential?

It is the voltage required to overcome the energy barrier for the charge transfer reaction at the electrode surface.

How do I calculate total voltage loss?

You can use the `calculate_total_overpotential` tool by providing the individual activation, concentration, and ohmic loss values.

Does this tool account for ohmic losses?

Yes, the `calculate_ohmic_loss` tool specifically calculates voltage drops caused by the internal resistance of cell components.
