On what factors does conductivity depend?

There are three main factors that affect the conductivity of a solution: the concentrations of ions, the type of ions, and the temperature of the solution.

Does resistivity depend on length?

Resistivity does not depend on the length of a material because it is a fix property of materials (only varies with temperature). Different types of materials have its own resistivity (for example: copper has a resistivity of 1.72×10 -18 ohm. m at 20 degree celcius).

What is conductor length?

Lay length is defined as the distance required to complete one revolution of the strand around the diameter of the conductor. When a conductor has more than one layer, it usually refers to the lay length of the outer layer. In the case of Unilay, Equilay and bunch, the lay length of all layers is equal.

What is the formula of conductance?

Conductance is the reciprocal of resistance as it is calculated as a ratio of current ‘I’ passing to the potential difference ‘V’. Ohms law is used to define the conductance. The unit of conductance is Siemens (S) or mho. Therefore, the conductance G = I/V=1/R mho or S.

Does resistivity decrease with length?

Resistivity is a property of a material and does not change with length though it may change with temperature. You can also say that the resistivity of a material is fixed or constant at a given temperature.

Why resistivity does not depend on area and length?

Larger cross sections have less resistance, and longer conductors have more resistance. Therefore, by multiplying resistance by area and dividing by length, you get a value for a material property (resistivity ρ) that doesn’t depend on the size of the conductor.

How do you determine lay length?

The length of lay is given by dividing the two quantities (length of rope , number of strands).

What is lay length?

Lay length is defined as the distance required to complete one revolution of the strand around the diameter of the conductor. When a conductor has more than one layer, it usually refers to the lay length of the outer layer.

How is conductance measured?

Conductance is the opposite of resistance: the measure of how easy it is for electric current to flow through something. Conductance is symbolized with the letter “G” and is measured in units of mhos or Siemens. Mathematically, conductance equals the reciprocal of resistance: G = 1/R.
