With an AMPD meter using 1% voltage radar
You measure the flow of energy over the potential difference of the medium. In electricity you would measure volt vs amp and find out electrical conductance. In thermal, you would measure temperature difference vs watt of energy transfer.
by measuring the conductivity
Conductivity - is measure in inverse amps.
Thermal conductivity refers to the measure of the ability of a material to allow the flow of heat from its warmer surface to its colder surface. The thermal conductivity of cast iron is 80 Wm-1K-1.
That really depends on what you want to measure about the apple: its weight, mass, diameter, albedo, electrical conductivity, etc.
*Electrical conductivity or specific conductivity [sigma] is a measure of a material's ability to conduct an electric current. When an electrical potential difference is placed across a conductor, its movable charges flow, giving rise to an electric current. The conductivity σ is defined as the ratio of the current density J to the electric field strength E : J=Sigma.E
i have to measure the conductivity of an electrolyte membrane made of polymer how can i do it using lab technique
A conductometer (conductivity meter) is an instrument designed to measure the electrical conductivity.
electical current
Oceanographers measure the salinity of the ocean by hand held refractometer, hydrometer, and conductivity meter.
Siemens is a unit of conductivity - it is the reciprocal of resistance. Mhos is also used for this measure.

by measuring the conductivity
We need to measure the electrical conductivity.
Conductivity is a measure of the ability of a substance to conduct electricity. Resistivity is a measure of how strongly a substance resists the flow of an electric current. So conductivity and resistivity are opposed to each other. A good conductor like copper has a low resistivity, and a good insulator like glass has a low conductivity and a high resistivity. Mathematically, conductivity and resistivity are inverses of each other, so it is quite easy to convert conductivity to resistance.
A PH meter measures conductivity to tell the amount of Hydrogen in a solution. A conductivity meter is used to measure the purity of water in ohms. A battery is a great example of solution conductivity at work.
Conductivity - is measure in inverse amps.
The answer depends on what you want to measure: its mass, length, "equatorial" circumference, volume, density, temperature, conductivity, ...
