How do ohmmeters work
WebOhmmeters are available in two forms i.e. the digital ohmmeter and the analogue ohmmeter. The digital ohmmeter displays the value of unknown resistance digitally, in the form of numeric digits. And the analogue ohmmeter displaces the value through a moving needed on a marked scale. WebMar 28, 2006 · You could use one to measure specific conductor resistivity and because most of these micro ohmmeters also measure voltages down to nV range, they are also invaluable in high precision lab works and semiconductor characterisations. These are the ones that I know and I have no doubt that they are also useful in many other applications. …
