Three factors that affect the resistance of a copper wire -?
There are three main factors that affect the resistance of a copper wire: Length of the wire: The resistance of a wire is directly proportional to its length. As the length of the wire increases, the resistance also increases. This is because the longer the wire, the more obstacles (collisions with electrons) the current has to overcome, resulting in higher resistance. Cross-sectional area of the wire: The resistance of a wire is inversely proportional to its cross-sectional area. As the cross-sectional area of the wire increases, the resistance decreases. This is because a larger cross-sectional area provides more space for the flow of electrons, reducing the resistance. Resistivity of the material: The resistance of a wire is also dependent on the resistivity of the material it is made of. Resistivity is an inherent property of the material and is a measure of how much the material opposes the flow of electric current. Copper has a relatively low resistivity compared to other metals, making it a good conductor and suitable for wiring applications. The relationship between these factors and the resistance of a copper wire can be expressed by the formula: R = ρ × (L / A) Where: R is the resistance of the wire ρ (rho) is the resistivity of the material (in this case, copper) L is the length of the wire A is the cross-sectional area of the wire By adjusting these three factors, you can control and manipulate the resistance of a copper wire to suit your specific needs in electrical and electronic applications.
What are the two factors of a wire that will alter its resistance?
The resistance of the wire is directly proportional to the length and inversely proportional to the area of cross section. Also it depends on the material of the wire with which it is made. So three factors. Length, area of cross section, material.
What three factors affect the amount of air resistance acting on an object?
shape, size, and speed
How do you calculate the joint resistance in a series circuit with three resistances?
The resistance of a series circuit is simply the sum of the individual resistors.
What three factors affect the amount of air resistance acting on a object?
Speed, shape and frontal cross-section.
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.
Factors affecting movement?
Three factors that affect movement are friction, wind resistance, and velocity. Friction is the resistance that a single object encounters when moving over another object. Velocity is speed, and wind resistance is the opposing force on an object.
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.
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.
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 are three factors affect how fast a river flows?
the three factors that affect how fast a river flows is the steep ,width and depth and how it is curved
Three Factors that affect the planning process?
Three factors that affect the planning process in an organization is lack of team work, communication, and motivation.
List three factors that affect salinity in the ocean and three factors that affect ocean temperatures. Explain how each factor affects salinity or temperatures?
Three factors are evaporation and freezing of sea water.
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
