WebDec 28, 2024 · An ohmmeter is a voltmeter along with a precision current source. Voltmeters are a known quantity, we all sort of know how low and precise you can reasonably go without too much noise, instability or cost. See TiN 's nanovoltmeter thread for a good idea what the ultimate limitations are. WebSep 4, 2015 · \$\begingroup\$ That's how I do that indeed :-) I would like to add that if Rl is very low you would need a very small value for V also because I = V/R so the current would become very large. So what I do is add a (power) resistor in series with the supply so that the maximum current is limited, for example to 1A. In case you have only one multimeter that … c tire cranbrook

A high resistance wire can measure around 5,000 ohms per foot, while a low resistance wire can easily fall in the 2-digit ohm per foot range. Here are some generic examples of plug wire resistance per foot: Copper core wire: 1-6,500 ohms. Inductive wire: 650-2,500 ohms. earthmover tires price
