the resistance of a cell, accumulator, etc, usually given as (E-V)/I, where E is the emf of the cell, and V the potential difference between terminals when it is delivering a current I
internal resistance in American English
noun
Electricity
the resistance within a battery, or other voltage source, that causes a drop in the source voltage when there is a current

Based on this, the calculation method of internal resistance of retired cells was developed.

However, the internal resistance of a battery can represent this difference.

Thus, only the existence of the internal resistance could account for this large discrepancy between model and measurements.

The internal resistance varied mainly as a result of changes in the battery temperature and charging current.

In the second case, different flow rates are used during the experiment to infer the internal resistance.

Simulation experiments based on the change of the internal resistance of the flow-induced voltagewere carried out.
