WebMar 9, 2015 · I think most low cost meters do the same (those with a most sensitive DC scale of 200mV). Thus you divide 200mV by the resistance scale setting to get the (constant) current used to measure the resistance. For example, at the 20kΩ scale setting, the current would be 200mV / 20kΩ = 10μA WebJul 27, 2024 · How Do Multimeters Measure Resistance? The basics are simple: the meter supplies a fixed current to the resistance and measures the voltage across it. See Figure 2. Ohm's law: voltage equals current times resistance (V = I x R). Switching the range changes the current—higher for low resistances. The meter scales the reading to show ohms.

WebAn ammeter is connected in series with the circuit to be measured. The ideal ammeter will have zero resistance so as not to disturb the circuit. We will find the shunt as part of the ammeter circuit. The "shunt" is nothing more than a resistor with a very low resistance.
