Measuring Resistance
An instrument for measuring resistance is called an ohmmeter. Simple ohmmeters cannot measure low resistances accurately because the resistance of their measuring leads causes a voltage drop that interferes with the measurement, so more accurate devices use four-terminal sensing.

Famous quotes containing the words measuring and/or resistance:
“By measuring individual human worth, the novelist reveals the full enormity of the State’s crime when it sets out to crush that individuality.”
—Ian McEwan (b. 1938)
“How is freedom measured, in individuals as in nations? By the resistance which has to be overcome, by the effort it costs to stay aloft. One would have to seek the highest type of free man where the greatest resistance is constantly being overcome: five steps from tyranny, near the threshold of the danger of servitude.”
—Friedrich Nietzsche (1844–1900)
