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)
“Even the most subjected person has moments of rage and resentment so intense that they respond, they act against. There is an inner uprising that leads to rebellion, however short- lived. It may be only momentary but it takes place. That space within oneself where resistance is possible remains.”
—bell hooks (b. c. 1955)
