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. WebFor resistance higher than 1.9999 Tera ohms, the conductance range can be used to measure conductance down to 0.01 pS (100 T ohms ). The meter has a conductance …
