What is the resistance of a 6 000 foot piece of 1 0 copper wire?
The answer depends on the cross sectional area of the wire. This is not given.
What is the equation for the length and resistance of a wire?
R = (density)(Length)/(Area) Unit of resistance is Ohms.
How does the cross sectional area of wire affect resistance?
Other things being equal, more cross-sectional area will cause less resistance.
Is the copper wire positive or negative?
copper is positive
How does resistivity vary if length and area are doubled?
if length is doubled then resistivity increases&when area is doubled resistivity decreases.
Would have the same resistance as a copper wire that is 4 m long and has a cross-sectional area of 0.066 cm2?
A wire with the same resistance as the given copper wire would have the same resistivity as copper. The resistance of a wire is dependent on its resistivity, length, and cross-sectional area. To calculate the resistance of a wire, use the formula R = (resistivity * length) / area; however, without the specific resistivity value, an exact value cannot be provided.
What would not reduce resistance in the copper wire?
Increasing the length of the wire will not reduce resistance in a copper wire. In fact, resistance is directly proportional to the length of the wire according to the formula R = ρ * (L/A), where R is resistance, ρ is resistivity, L is length, and A is cross-sectional area.
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.
Which material has a greater resistance aluminum or copper wire?
Copper wire has greater resistance than aluminum wire. This is because copper is a better conductor of electricity than aluminum. This means that copper wire will have less resistance and will be able to carry more current with less energy loss.
What has the lowest resistance copper wire or iron wire?
Copper wire has lower resistance compared to iron wire. This is because copper is a better conductor of electricity due to its higher electrical conductivity and lower resistivity.
What is the resistance value of 1 meter copper wire?
The resistance value of a 1 meter copper wire depends on its gauge (thickness) and temperature. For example, a 1 meter wire of 24-gauge copper has a resistance of about 25.67 ohms at room temperature. It is important to consider these factors when calculating the resistance of copper wire.
What is the resistance of a 6 000 foot piece of 1 0 copper wire?
The answer depends on the cross sectional area of the wire. This is not given.
Can copper and alluminium wire of same length and diameter have same resistance?
No, copper and aluminum wire of the same length and diameter will not have the same resistance. Copper has a lower resistivity than aluminum, so a copper wire will have lower resistance compared to an aluminum wire of the same length and diameter.
What are the dependent variables in a copper wire resistance experiment?
The dependent variables in a copper wire resistance experiment would typically be the resistance of the copper wire being measured. This would vary based on factors like the length and thickness of the wire, as well as the temperature.
Which conditions make resistance small?
The resistance of a wire is the length divided by the cross-section area and the conductivity of the material. So for small resistance you need a wire with short length, large cross-section area (diameter) and a material with high conductivity like copper.
Does a thin wire has more RESISTIVITy or a thin wire of the same material?
A thin wire will have more resistance than a thicker wire made of the same material because resistance is inversely proportional to cross-sectional area. Thinner wires have a smaller cross-sectional area, leading to higher resistance.
Does a short copper wire have more resistance then a long one?
No, resistance depends on the material, cross-sectional area, and temperature of the wire. A shorter wire will have less resistance compared to a longer wire since it offers less opposition to the flow of electrical current.
