Aims of the Experiment The overall aim of the experiment is to investigate the relationship between e.m.f and internal resistance by measuring the variation of current and voltage using a variable resistor Independent variable = resistance, R (Ω) Dependent variable = voltage, V (V) & current, I (A)
The internal resistance provides valuable information about a battery as high reading hints at end-of-life. This is especially true with nickel-based systems. Resistance measurement is not the only …
Measuring the internal resistance of a battery is important to ensure that it is in good condition and to monitor its performance over time. The two most commonly used methods for …
Calculate the Internal Resistance Using the voltage readings from the "10k Ω Load" and the "No Load" (open circuit), calculate the internal resistance of the lemon battery. Hint: Refer to the Internal Resistance section to see how to …

There are several methods to measure a battery''s internal resistance. Here, we''ll discuss two common techniques: The DC Load method and the AC …
Then, internal resistance of the battery can be determined to be around 240mOhm. Hence, my battery can theoretically discharge the current as high as 4.2V/0.24=17.5A (short circuit maximum current at fully charged state) but it is not good to do so.
The DCIR of a cell is the Direct Current Internal Resistance. This is the resistance in charge and discharge to a direct current demand applied across the …
You can measure the internal resistance of a battery without EMF by using a resistor in series with the battery and measuring the voltage drop across the …
