Strain gauges operate by detecting changes in this quantity, because it is proportional to length and inversely proportional to cross-sectional area.
The Kondo effect describes this quantity's divergence at low temperatures. Strain gauges operate by detecting changes in this quantity, because it is proportional to length and inversely proportional to cross-sectional area. Its AC-circuit extension is the complex quantity impedance, and its inverse, measured in siemens, is the conductance. Equal to voltage divided by current, according to Ohm's law, it is high for insulators and low for conductors. For 10 points, name this measure of how much an object opposes electric current.
