8.6.1 Example
To measure the internal resistance of a 9 V battery, we need to measure the voltage of the
battery first.
The measured voltage in this figure is 8.97 V DC.
Second, we connect a resistor with the battery and measure its voltage, in our case we will
connect a 510 Ω resistor.
The measured voltage in this figure is 8.59 V DC.
