Circuit for measuring resistance
WebResistance is measured with the circuit’s power turned off. The ohmmeter sends its own current through the unknown resistance and then measures that current to provide a resistance value readout. Role of the Battery Even though it reads out resistance, the ohmmeter is still a current-measuring device at heart. WebMar 30, 2024 · Different from the clean vacuum environment, in the open environment the junction of the resistance measuring circuit absorbs oxidizing gas, acid gas, water molecules, dust and other substances. It is found that the thermoelectric and chemical electrodynamic potentials of the measuring circuit have different behaviors with the time.
