Ohmmeter High Impedance at Gladys Gill blog

Ohmmeter High Impedance. Once you have your buffer, get another. • an electrometer’s voltmeter function and a current source. The meter scales the reading to show ohms. In some meters the details are different, but the basic concept still applies. For analog ohmmeters, the needle will move to indicate the resistance. Voltage equals current times resistance (v = i x r). A very high impedance amplifier is national's lmp7721, requiring only 3 femtoamps of bias current. When measuring voltage, you connect the voltmeter (a multimeter in voltmeter mode). Switching the range changes the current—higher for low resistances. For digital ohmmeters, the reading will be displayed.
