What is thermal resistivity of soils?
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.
What is the luster of a graphite?
Graphite is black and posseses dull appearance
What is slippery carbon?
Graphite Powder or graphite is the slippery type of Carbon! :) hope I helped! :P
What mineral is used in pencils?
Graphite.
What is graphite made of?
Graphite is a form of carbon.
What are the factors that effects the conductivity of pencil lead?
The percentage amount of graphite used affects the conductivity of pencil "lead". More the amount, lesser is its resistivity and greater the conductivity.
Is pencil lead a resistor?
It is not a resistor, but not to say it's a good conductor. Although it lacks the metallic bonding that makes Cu such a good conductor, the sheets of graphite have hybridized sp2 orbitals, meaning there are long rows of p orbitals that can share electrons across the sheet, meaning it can conduct electricity. It has a resistivity of ~20uOhm meters, whereas as Cu has a resistivity of ~17nOhm meters.
What is thermal resistivity of soils?
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.
Do wires that have high resistivity have high conductivity also?
No. In fact it is the opposite. Conductivity is the reciprocal of resistivity so a high resistivity means low conductivity. peace.
What are the formulae of resistivity?
There is no 'formula' for resistivity. The resistivities of different conductors have been determined by experiment.
What change in resistivity if length is doubled?
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.
What is the value of resistivity of human skin?
The value of resistivity of human skin is 0.2 Ohm-meters
What is a form of carbon that makes a good lubricant?
Graphite (I think)
How do you convert conductivity to resistivity?
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.
What is the difference between carbon graphite and graphite?
because carbon graphite had carbon but graphite does not have carbon
What is resistivity and what factor does it depend?
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.
If a wire of resistivity is stretched to thrice its initial length what will be its new resistivity?
the resistivity will increase by nine times
