A battery's internal resistance is determined by (OCV = Open Circuit Voltage, CCV = Closed Circuit Voltage)
- IR = (OCV - CCV)/ i.
- IR = (OCV + CCV) / i.
- IR = (OCV - CCV) / V.
Explanation from PART66Online
Internal resistance is found from the drop in terminal voltage when a load current flows. The open-circuit voltage minus the closed-circuit (loaded) voltage gives that drop, and dividing by the load current i yields the resistance: IR = (OCV - CCV)/i. Adding the voltages, or dividing by V instead of the current, is dimensionally wrong.
