How does a meter measure resistance
WebResistance is the measure of electrical “friction” as charges move through a conductor . It is measured in the unit of ohm, that unit symbolized by the capital Greek letter omega (Ω). Parts and Materials Multimeter, digital or analog Assorted resistors Rectifying diode Cadmium Sulphide photocell Breadboard Jumper wires Paper Pencil Glass of water WebMay 19, 2011 · If you have 1.5 cm of liquid between the two plates, then A/L = 210. If your meter reads 100K Ohms, then you know the resistivity is 210 x 100K = 21M Ohms. By the way, the conductivity I found for "ultra-pure" water is 18.2M (Ohm x cm). I forget if that is before or after exposure to air.
