WebThe difference in electric potential between two points. That's why we hook up voltmeters in parallel and because we hook up voltmeters in parallel, voltmeters have to have a huge resistance. Sometimes on the order of hundreds of thousands of ohms or even millions of ohms. So this can be big, big number of ohms. Web15 de out. de 2024 · For older meggers, the method was a hand-crank generator that could build up a huge voltage, sometimes well above 1000 volts. For digital meters, the step-up is done with a DC-DC voltage converter. These can still yield a high voltage, although 1000 volts is usually about the largest typical voltage on a digital mega-ohmmeter. Figure 2.
