Resistivity is equal to the product or resistance n area over divided over length ....is dimension is [m^1 l^3 t^-4 a^-3]
no its depends on material properties.
Resistivity is a property of a substance, and doesn't depend on the dimensions of a sample. If the length of a conductor is doubled, then its resistance doubles but its resistivity doesn't change.
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.
Electrical resistivity (also known as resistivity, specific electrical resistance, or volume resistivity) quantifies how strongly a given material opposes the flow of electric current. A low resistivity indicates a material that readily allows the movement of electric charge. Resistivity is commonly represented by the Greek letter ρ (rho). The SI unit of electrical resistivity is theohm⋅metre (Ω⋅m)It defined as resistance offerde by a unit length and cross section area conductor.It depends on material used.it depends on relexation time and temperature.
the resistivity will increase by nine times
no its depends on material properties.
Its depending on cable dimension, current carring capacity and soil thermal resistivity.
The resistivity of graphite is 7.837 µΩm.
Resistivity is the opposite of conductivity. The thermal resistivity of soil is the degree to which soil impedes the flow of heat, or insulates against heat.
No. In fact it is the opposite. Conductivity is the reciprocal of resistivity so a high resistivity means low conductivity. peace.
There is no 'formula' for resistivity. The resistivities of different conductors have been determined by experiment.

The value of resistivity of human skin is 0.2 Ohm-meters
