What are the conventional formulae?
When a sample of germanium and silicon having same impurity density are kept at room temperature then resistivity of both?
The resistivity of germanium will decrease with increasing temperature due to a positive temperature coefficient of resistivity, while the resistivity of silicon will increase with increasing temperature due to a negative temperature coefficient of resistivity. At room temperature, silicon will have a higher resistivity compared to germanium.
What are the formulae used in mathematics?
There are thousands of mathematical formulae.
Does high resistivity have a higher number or lower number?
High resistivity corresponds to a higher numerical value. In the context of materials, resistivity is a measure of how strongly a material opposes the flow of electric current; materials with high resistivity, like rubber or glass, have larger resistivity values compared to conductive materials like copper or aluminum, which have low resistivity values.
If the diameter of wire is double what is resestivity?
Resistivity won't change. Resistivity is a material property that doesn't depend on the shape.
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.
Can resistivity be negetive?
No, resistivity cannot be negative. Resistivity is a material property that indicates how strongly a material opposes the flow of electric current. It is always a positive quantity, even though some materials may have very low resistivity values.
What is the resistivity of deionized water and how does it compare to the resistivity of other types of water?
The resistivity of deionized water is high, meaning it is a good insulator. It is higher than the resistivity of tap water or seawater, which have more dissolved ions and conduct electricity better.
Formulae in derivative?
You will find several formulae in the Wikipedia article on "derivative".
What is resistivity on what factor is depends?
Resistivity is a measure of a material's ability to resist the flow of electric current. It depends on factors such as the material's composition, temperature, and dimensions. Materials with high resistivity impede the flow of current more than those with low resistivity.
How are materials classified on the basis of resistivity?
Materials can be classified based on their resistivity as conductors, semiconductors, or insulators. Conductors have low resistivity, allowing electric current to flow easily. Semiconductors have resistivity in between conductors and insulators, and their conductivity can be controlled. Insulators have high resistivity and do not allow electric current to flow easily.
What is the value of resistivity of human skin?
The value of resistivity of human skin is 0.2 Ohm-meters
