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. Resistivity is commonly represented by the Greek letter ρ (rho). The SI unit of electrical resistivity is the ohm⋅metre (Ω⋅m) although other units like ohm⋅centimetre (Ω⋅cm) are also in use. As an example, if a 1 m × 1 m × 1 m solid cube of material has sheet contacts on two opposite faces, and the resistance between these contacts is 1Ω, then the resistivity of the material is 1Ω⋅m.
Electrical conductivity or specific conductance is the reciprocal of electrical resistivity, and measures a material's ability to conduct an electric current. It is commonly represented by the Greek letter σ (sigma), but κ (kappa) (especially in electrical engineering) or γ (gamma) are also occasionally used. Its SI unit is siemens per metre (S/m) and CGSE unit is reciprocal second (s−1).
Electrical conductivity is the ability of a material to conduct electricity.
Take an electrical circuit consisting of a bulb, cell, wire and a switch.
Connect wood to the circuit.
The bulb does not glow indicating that wood is a poor conductor of electricity.
Connect a paper roll to the circuit.
The bulb does not glow, indicating that paper is also a poor conductor of electricity.
Take a metal like iron and connect it in the same circuit.
The bulb glows indicating that iron is a good conductor of electricity.
Similarly, other metals like copper, silver, etc. also make good conductors of electricity.
Hence, we can say that most metals are good conductors of electricity.

Metallic Bonding and the Electron Sea Model, Electrical Conductivity - Basic Introduction
This chemistry video tutorial provides a basic introduction into metallic bonding and the electron sea model. The valence electrons in the metal are delocalized - they are free to move around stationary metal cations. This explains the electrical conductivity of metals. A substance with free flowing charge can conduct an electric current. The charge carrier in metals are valence electrons. The core electrons in metals atoms are localized - they are bound to their respective atoms and are not free to move from one metal atom to another.

ELECTRICAL CONDUCTIVITY:Electrical conductivity is a measure of how well a material accommodates the movement of an electric charge. Its SI derived unit is the Siemens per meter.The materials, which allow electric current to pass through them, are good conductors of electricity. On the other hand, materials, which do not allow electric current to pass through them easily, are poor conductors of electricity.You know that metals such as copper and aluminium conduct electricity whereas materials such as rubber, plastic and wood do not conduct electricity.Good conductors have high electrical conductivity than insulators.

ELECTRICAL CONDUCTIVITY:Electrical conductivity is a measure of how well a material accommodates the movement of an electric charge. Its SI derived unit is the Siemens per meter.The materials, which allow electric current to pass through them, are good conductors of electricity. On the other hand, materials, which do not allow electric current to pass through them easily, are poor conductors of electricity.You know that metals such as copper and aluminium conduct electricity whereas materials such as rubber, plastic and wood do not conduct electricity.Good conductors have high electrical conductivity than insulators.
In this video, Ethan gives an in depth explanation of electrical conductivity. He also explains how and why you need to properly manage EC in your farm.
Ethan shows how proper EC balance will allow you to grow healthy crops in your farm, gives details on how to manage EC, and explains EC's units and how they can be measured.

In this video I test water conductivity with a simple experiment which shows how water changes its conductivity when you add salt to it. (Also I added sugar to see what happen)
This is a simple conductivity test of liquids.
WARNING: Do not try to repeat The Experiment yourself, it can be dangerous.

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. Resistivity is commonly represented by the Greek letter ρ (rho). The SI unit of electrical resistivity is the ohm⋅metre (Ω⋅m) although other units like ohm⋅centimetre (Ω⋅cm) are also in use. As an example, if a 1 m × 1 m × 1 m solid cube of material has sheet contacts on two opposite faces, and the resistance between these contacts is 1Ω, then the resistivity of the material is 1Ω⋅m.
Electrical conductivity or specific conductance is the reciprocal of electrical resistivity, and measures a material's ability to conduct an electric current. It is commonly represented by the Greek letter σ (sigma), but κ (kappa) (especially in electrical engineering) or γ (gamma) are also occasionally used. Its SI unit is siemens per metre (S/m) and CGSE unit is reciprocal second (s−1).
