No. The resistance in different materials is different. For example, Copper has a low resistance to electricity compared to plastic. This is also one reason why copper is used instead of plastic in wires. Knowing the resistance of different material helps decide what material should be use for different objects (like copper for wires in plastics)
What else can I help you with?
How do you calculate a cross-sectional area When all you know is resistance resistivity and length?
I think the equation you are looking for is Resistance (ohms) = Resistivity * Length / Area or R=p*L/A. This is the resistance of a circular wire with cross-section of A, length of L, and material with resistivity p. So to get area: Area = Resistivity * Length / Resistance.
Do all materials of the same length have the same cross sectional area?
No.
What three primary factors influence electrical resistance of circuit?
The resistance of any material is affected by its length, cross-sectional area, and resistivity. As resistivity varies with temperature, resistance is indirectly affected by temperature.Specifically, resistance is directly proportional to length and inversely proportional to cross-sectional area, and resistivity is the constant of proportionality.These factors apply to the conductors and all the components of your 'circuit' -including any insulation.
Five factors that affect resistance?
Electrical Resistance depends on three factors: Resistivity; Area; Length.Resistivity is the property of the matter. More Resistivity means more resistance.More Area means less resistance.More length means more resistance.R= Resistivity. Length/Area
Does every different conducting substance have a unique resistivity?
Please note that resistivity also depends on temperature.In the most general case, the answer is definitely NO; all superconductors have the same resistivity, namely zero. Other than superconductors, take a look at a table with some typical resistivity values. It would seem quite obvious that for a given temperature: * Two different substances will, in general, have different resistivities. * In practice, in some cases the difference in resistivity might be too small to reliably measure. * It should be possible to find two substances that have the same resistivity at a very specific temperature - since the temperature-dependence will vary from one material to another. * Likewise, it should be possible to design a mix of two substances, which exactly matches that of another, given, substance.
Why are all the diameters of a circle the same length?
They are not all the same length. If that was the case all circles would be the same size.
What was the length of the trireme?
They were not all the same length.
Does a hexagon have the same length on all sides?
In general no. A regular hexagon has the same length on all sides. Also, there are other hexagons with the same length on all sides that are not regular.
A polygon with all sides the same length and all angles the same measure is called?
a polygon with all sides the same length and all angles the same measure is called?
Is Materials that do not conduct electrical charges at all are called insulatorst?
Yes, materials that do not conduct electrical charges at all are called insulators. Insulators have high resistivity and prevent the flow of electric current. Examples of insulators include rubber, glass, and plastic.
Are all fixed length files are of the same length?
No. No. No. No.
Are squares allwats the same?
All squares have four right angles and all sides the same length. All squares having the same side length are the same.
