Conductivity of any substance is measured by inducing an electric charge or power supply of some sort with known quantity on one side of the time and measuring the resulting charge, if any exists, after the charge flows through the substance.
If you picture a straight wire strand of gold, we induce a known charge on the left side of the wire, then measure the resulting charge on the right side of the wire.
This is also how a basic ohm-meter works. By placing two leads on either side of the wire, a circuit is formed using the meter and the connection point. One of the ohm-meter leads induces a small charge, the other reads the result. Using Ohms law (E=IR or V=IR, which is electro-magnetic force equals current * resistance, or voltage), the meter displays the amount of resistance in the circuit of substance.
The higher the amount of the electric charge to pass through, the less resistance the substance has. The lower the amount of charge led to pass through, the more resistance. Infinite resistance defines insulators, while minimal resistance defines conductors.
Once resistance is known, conductivity is a factor of both the resistance of the material and the size of the material used, or o = l/RA. l is the length of the sample (in meters), R is the resistivity (in ohms) and A is the area of the sample (in square meters). This will give us the conductivity o (in ohm meters^-1). The official unit of measure for electrical conductance is the siemens (S) which is defined as an inverse ohm (ohm^-1).

What is the next highest degree of electrical conductivity other than silver?
Gold is incredibly conductive, which is why gold-plated wires tend to be more prized.
What are the metric measurements of a gold nugget?
The answer depends on what characteristic of the gold nugget you wish to measure: its mass, weight, volume, density, temperature, electrical conductivity, etc.
What is molar conductivity at infinite dilution?
Molar conductivity at infinite dilution is when molar conductivity is limited. Molar conductivity is when electrolyte conductivity is divided by molar concentration.
What metals have thermal conductivity?
ALL metals are pretty good conductors of heat. Some, like gold, are very good conductors of heat.
Why do oceanographers take measurements of the conductivity of the seawater?
Conductivity can be used to calculate the salinity of the water.
What factor was used to determine conductivity of matter?
No
Do neutrons determine the conductivity of the atom?
no, but they determine if it is an isotope or not
Which metal has the highest electrical conductivity value?
gold
What is gold's conductivity?
Gold is the most conductive of metals. It has an electrical conductivity of 4.1 x 107 Siemens per meter (S m-1)
What are the differences in tin and gold edged memory sticks?
Conductivity
Why gold is good conductor of electricity?
The conductivity (how well a material conducts) of a material depends on the density of its free electrons (number of free electrons per unit volume). The best metal conductor is silver. Copper's conductivity is 95% that of silver. Gold's conductivity is 65% that of silver. So, as you can see, gold is by no means the 'best' conductor.
How can I see the difference between gold and copper?
Copper and gold are different metal elements with different properties. The thermal conductivity of gold is 318W/mK, whereas the thermal conductivity of copper is slightly higher at 401W/mK. The electrical conductivity of copper is slightly higher at 5.96 x107 S/m than gold which is 4.11×107 S/m.
What purity of gold is required for computers?
To get the right conductivity you need the purest form of gold. The karot doesn't matter
Electrical conductivity of copper?
Copper in one of the most electrically conductive of substances. Few materials have more conductivity. These include platinum, gold, and silver.
What are the Factors that determine resistance value of electrical material?
The factors that determine resistance are thickness, length, temperature, and the conductivity of the resistance of an object
Do gold connectors enhance my computer's performance?
Cables with gold connectors are considered to increase conductivity, which usually increases speeds.
What is conductivity material?
This a material with a high thermal or electrical conductivity.Examples: silver, copper, gold.
