- Resistance refers to the property of a substance that impedes the flow of electric current. Some substances resist current flow more than others. If a substance offers very high resistance to current flow it is called an insulator. If its resistance to current flow is very low, it is called a conductor. Resistivity refers to the ability of substances to resist current flow. Good conductors have low resistivity and insulators have high resistivity.

- In physics, thermal conductivity (often denoted k, λ, or κ) is the property of a material to conduct heat. It is evaluated primarily in terms of Fourier's Law for heat conduction. Heat transfer occurs at a lower rate across materials of low thermal conductivity than across materials of high thermal conductivity. Correspondingly, materials of high thermal conductivity are widely used in heat sink applications and materials of low thermal conductivity are used as thermal insulation. The thermal conductivity of a material may depend on temperature.

Conductivity (electrolytic) Conductivity (or specific conductance) of an electrolyte solution is a measure of its ability to conduct electricity.The SI unit of conductivity is siemens per meter (S/m).he concentration of ions in a solution of a weak electrolyte is less than the concentration of the electrolyte itself. For acids and bases the concentrations can be calculated when the value(s) of the acid dissociation constant (s) is(are) known.

- It involves a swelling of the membrane that covers the eye. The result is the eye will discharge more water than normal. Often the fur around the eye will be wet and watered down, which is one of the easy signs for us to see that weepy eye may be present. Weepy eye may also be caused by a block duct within the eye. This can be caused by bacteria. Another possible cause may even be allergies that the rabbit has. Ocassionally you’ll find that the rabbits front paws are also wet from constantly wiping their eyes.

- Resistance and conductivity. The resistance of a conductor is a measure of the opposition to the current flowing in it. The resistance will increase as the length of the conductor is increased and the resistance falls as the diameter of the conductor increases.

- Resistance and conductivity. The resistance of a conductor is a measure of the opposition to the current flowing in it. The resistance will increase as the length of the conductor is increased and the resistance falls as the diameter of the conductor increases. The value of resistance is measured in ohms.

Water and Soil Characterization - pH and Electrical Conductivity Lower pH corresponds with higher [H + ], while higher pH is associated with lower [H + ]. Electrical conductivity (EC) is a measurement of the dissolved material in an aqueous solution, which relates to the ability of the material to conduct electrical current through it.

- Electrical Conductivity is the ability of a solution to transfer (conduct) electric current. It is the reciprocal of electrical resistivity (ohms). Therefore conductivity is used to measure the concentration of dissolved solids which have been ionized in a polar solution such as water.The unit of measurement commonly used is one millionth of a Siemen per centimeter (micro-Siemens per centimeter or S/cm).he TDS scale uses 2 S/cm = 1 ppm (part per million as CaCO3). It is also expressed as 1 mg/l TDS. While the method of measurement is the same, some conductivity meters can make the conversion and express the results of a measurement in many different units.

Electrical resistivity and conductivity Electrical resistivity (also known as resistivity, specific electrical resistance, or volume resistivity) is an intrinsic property that quantifies how strongly a given material opposes the flow of electric current. A low resistivity indicates a material that readily allows the flow of electric current.

- The definition of conduction is the movement of something such as heat or electricity through a medium or passage. An example of conduction is using a metal rod to roast marshmallows on an open fire and feeling the heat rise through the rod from the fire to your hand.

Electrical resistivity and conductivity A piece of resistive material with electrical contacts on both ends. Many resistors and conductors have a uniform cross section with a uniform flow of electric current, and are made of one material. (See the adjacent diagram.) In this case, the electrical resistivity ρ (Greek: rho) is defined as:

conductor Part of the Electronics glossary: An electrical conductor is a substance in which electrical charge carriers, usually electrons, move easily from atom to atom with the application of voltage. Conductivity, in general, is the capacity to transmit something, such as electricity or heat. Pure elemental silver is the best electrical conductor encountered in everyday life. Copper, steel, gold, aluminum, and brass are also good conductors.

- Electrical resistivity is a property of materials and is different from electrical resistance which is a property of a component. Resistivity is also known as Specific Electrical Resistance or Volume Resistivity. Resistivity can also be defined as the inverse of the conductivity of a material - ρ = 1 / σ.It is a measure of how a material opposes the flow of electric current. The SI unit of resistivity is ohm meter (ω.m).
