Electrical Principles
If the emf (ℰ) of a battery is known, its internal resistance ( R INTERNAL ) can be found by measuring the current ( I LOAD ) that flows across a load resistance ( R LOAD ) with a known value. Since the internal and load resistances are in series, we can use Kirchhoff''s voltage law and Ohm''s law to obtain the following formula:

6.2: Electromotive Force
For a given emf and internal resistance, the terminal voltage decreases as the current increases due to the potential drop Ir of the internal resistance. Figure (PageIndex{6}): Schematic of a voltage source and its load resistor R.Since the internal resistance r is in series with the load, it can significantly affect the terminal voltage and the current …
9B: Electric Current, EMF, and Ohm''s Law
The charge flow rate, how many coulombs-of charge per-second are crossing that line is called the electric current at that point. In the case at hand, because the whole circuit consists of a single loop, the current is the same at every point in the circuit—it doesn''t matter where you "draw the line."

Batteries Part 2
When a battery cell is open-circuited (i.e. no-load and R L = ∞Ω) and is not supplying current, the voltage across the terminals will be equal to E.When a load resistance, R L is connected across the cells terminals, the cell supplies a current I which causes a voltage drop across internal resistance R INT of the cell. ...
