What is internal resistance and how does it occur?
There are two basic components that impact the internal resistance of a battery; they are electronic resistance and ionic resistance. Is the internal resistance of a battery constant? As current decreasesd, voltage across the internal resistance of the cell, Ir, decreased (using V=IR), because internal resistance should remain constant.
