Resistivity of copper at 20 degree celsius?
Resistivity allows us to compare different conductors' abilities to transmit electric current that is independent of the physical dimensions of the conductors.Resistivity is defined as 'the resistance of a unit length of a substance with a uniform cross-section'. In SI, the unit of measurement of resistivity is the ohm metre; in US customary units, it is expressed in ohm circular mil per foot.So, to finally answer your question, the resistivity of copper is 17.5x10-9 ohm metres at 20oC. To find the resistance of a copper conductor, you can then use the equation:resistance = resistivity x (area / length)Additional AnswerThe resistivity of copper depends on the temperature it which it is measured. At 25°C, it is about 17 nΩ.m, or 1.7 µΩ.cm.The resistance of a conductor is then p * L / A, where p is the above number.So for a wire with a length of 1 m (i.e. 100 cm), and a cross sectional area of 2 cm², the resistance is 17e-6 * 100 / 2 = 85 µΩ
If three rocks have the same mass will the weathering rate be the same?
Not necessarily. Weathering rates would depend on the rock type, mineral composition, and density. These factors will determine a rock's resistance to acidic rainwater, freeze/thaw cycles, and abrasion.
Why is electrical resistivity important to a design engineer?
electrical resistance increases current flow decreases.so to know the current flow in the network ,electrical resistance is required.AnswerResistivity is important, because it is one of the three factors that affect the resistance of a material. The other factors are the length and cross-sectional area of the material.
What three factors determine the amount of resistance of a material?
In solids, the resistance varies directly as the length of the object and inversely as the cross-sectional ares of the object and coefficient of resistance of the material which is an inherent property that each solid (metal or other) has.
What three factors affect how much electrical resistance an object has?
Any load would do or anything that has resistance. Which is pretty much everything you can hook up to a circuit. For example, lightbulb, buzzer, resistor etc.
The electrical resistance of circuit is influenced by three primary factors?
Resistance is directly proportional to the resistivityand length of a material, and inversely-proportional to its cross-sectional area. It should also be noted that its resistivity is affected by temperature, so temperature indirectly affects resistance.
What are four factors that influence resistance?
The length of the material The cross-sectional area of the material The resistivity of the material The temperature of the material
What factors effect the resistance of a conductor?
Factors affecting the resistance of a conductor include the material from which it is made, its length, its cross-sectional area, and its temperature.
What are the two factors that determine the density of materials?
The two factors that determine a material's density (such as that of wood) are its mass and volume.
What are the two factors that determine a materials density of wood?
The two factors that determine a material's density (such as that of wood) are its mass and volume.
What are three related electrical factors did George Ohm investigate?
the answer is current, voltage, and resistance
Factors affecting resistance of a metal conductor?
The material, the length, the cross section.
What four factors determine the amount of resistance in a circuit?
Material that makes up the wire, length of wire, diameter of wire, and temperature of wire
What aree the factors that determine the strength of a material?
The element that made up that material and the microscopic structure.
