Is germanium a conductor of electricity?
Germanium is a semiconductor.
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.
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 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
What is the resistivity of germanium if they compared to glass?
glass is an insulator, germanium is a metalloid.
When a sample of germanium and silicon having same impurity density are kept at room temperature then resistivity of both?
Resistivity of silicon higher than that of germanium
What are semi conducting substances?
Those which have resistivity in between conductors and insulators are known as semi conductors. Germanium and Silicon are very good examples of semiconducting materials whose resistivity of the order of 10 -2 to 10 4 ohm meter.
What is the resistivity of graphite?
The resistivity of graphite is 7.837 µΩm.
Is germanium toxic?
Germanium compounds are toxic.
What does germanium do?
Germanium does no "do" anything.
Who is Germanium manufactured?
Germanium is not manufactured; its ore is mined then refined into germanium.
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.
Is germanium a insulator of electricity?
Germanium is a semiconductor
Is germanium reactive?
germanium reacts naturally
