Resistivity - A Level Physics
If I have two copper wires with the same diameter, but one is longer than the other, you can expect the longer wire to have a higher resistance.
That’s because an electron needs to make its way between more positive ions before it reaches the other end. This means resistance is proportional to the length of wire.
Two wires that have the same length but have different cross-sectional area will have different resistance. The larger the cross sectional area a wire has, the lower the resistance it has. Resistance is inversely proportional to area.
We also need a way to take into account the material's ability to impede the motion of electrons. This is called resistivity.

Resistivity and Resistance Formula, Conductivity, Temperature Coefficient, Physics Problems
This physics video tutorial explains the concept of resistivity and resistance of electrical conductors like copper and silver as well as semiconductors such as silicon, germanium, and carbon graphite. It provides the formula to calculate the resistance of a metal or wire using resistivity. It discusses the inverse relationship between resistivity and conductivity as well the direct relationship between resistance and temperature. Electrical conductors such as metals have a positive temperature coefficient of resistivity which means that as the temperature of a metal increases, the resistivity will increase and the conductivity will decrease. For metalloids or semiconductors, the opposite is true. These elements have a negative temperature coefficient which means that the resistance w...

Resistance & Resistivity, An Explanation
Goes over an explanation of resistance and resistivity. Includes a worked example.
Resistivity is a property of a material that tells you how strongly it resists or conducts the flow of electric current. A low resistivity indicates a material that 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-meter (Ω⋅m). Resistance of a conductor is directly proportional to the length of the conductor and inversely proportional to the cross-sectional area of the conductor.

Resistivity
017 - Resistivity
In this video Paul Andersen explains how the resistivity of a material opposes the flow of charge. Conductors (like metal) will have a low resistivity and insulators will have a high resistivity. Semiconductors will have a moderate resistivity. Since the resistivity is determined by the atomic and molecular structure it is affected by changes in temperature.

For metalloids or semiconductors, the opposite is true. These elements have a negative temperature coefficient which means that the resistance will decrease as the temperature increases which correlates to an increase in conductivity. The resistivity depends on the length of the wire as well as the cross sectional area. Long wires have more resistance and short wires conduct electricity better. Thick wires have less resistance than thin wires. This video shows you how to calculate the temperature by simply measuring the current in a metal using a known voltage which has practical applications in digital thermometers.

How to calculate factors affecting the resistance of a material
This explains how to calculate factors affecting the resistance of a material, length, area, resistivity and temparature. It provides the formula to calculate the resistance of a metal or wire using resistivity. It discusses the inverse relationship between resistance and area , the direct relationship between resistance and length, as well as resistance and temperature. Electrical conductors such as metals have a positive temperature coefficient of resistivity which means as the temperature increase so will the resistance of a conductor. For metalloids, the opposite is true. These elements have a negative temperature coefficient, which means as my temperature increase my resistance will decrease. The resistivity depends on the length, cross-sectional area and temperature of a conductor. This video shows examples of how to manipulate the standard formula to calculate length, area, resistivity and resistance. It also shows how to calculate temperature.
