Turn digital multimeter dial to resistance or ohms which often shares a spot on the dial with one or more other testmeasurement modes continuity capacitance or diode.
How To Measure Resistance With A Digital Multimeter Fluke from www.fluke.com
Quoting from wikipedia To measure resistance a small battery within the instrument passes a current through the device under test and the meter coil. Pick out a random resistor and set the multimeter to the 20kΩ. Using the 2 probes of my multimeter placing the red probe on my left thumb and black probe on my right thumb I measured about 1 mega ohm for my body resistance.
Where e is the electromotive force Volts I is the current A R is the load resistance and r is the cells internal resistance measured in ohms.
Calculate the Internal Resistance. Your idea of measuring it with DMM in Ohmmeter mode is absolutely wrong. Internal resistance in this video there is description about how we can measure the internal resistance of the battery with help of digital multimeterFor mo. Calculate the Internal Resistance.
