The correct answer is 0.033 ohms.
resistance is directly proportional to wire length and inversely proportional to wire cross-sectional area. In other words, If the wire length is doubled, the resistance is doubled too. If the wire diameter is doubled, the resistance will reduce to 1/4 of the original resistance.
The key parameter in sizing wire is the current requirement. Once you know that you can look up value in a wire gauge table. The length of the run is important for longer runs because of the resistance of the wire itself. Aluminum wire requires a larger diameter than copper for the same current. Once you calculate the wire size you can then size the conduit.
(rho) or resistivity of a "wire" is calculated using this formule:rho = Resistance x Area / length of materialthe resistivity of copper is 1.7 x 10 -8 ohm/mResistivity is measured in ohm metres, NOT ohms per metre!
The current capacity varies depending on the length and diameter of the wire
Resistance depends on the thickness and length of the wire used, as well as the conductor used. For example, a short, thick wire made of copper will conduct electricity better than a long, thin wire made of, say, iron.AnswerResistance is directly proportional to the length and inversely proportional to the cross-sectional area (not 'thickness') of a material. Its constant of proportionality is called resistivity which is affected by temperature -so temperature indirectly affects 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.
Is either; A. the length of the wire B. the diameter of the wire c. the location of the wire D. the temperature of the wire
High resistance in a copper wire can be caused by factors like a longer wire length, a thinner wire diameter, and the material's high temperature, which increases resistance due to increased collisions among electrons.
The resistance of a wire is directly proportional to its length, so if the length is reduced by half, the resistance will also be reduced by half.
If both the diameter and length of a wire are quadrupled, the resistance of the wire will increase by a factor of 16. This is because resistance is directly proportional to the length of the wire and inversely proportional to the cross-sectional area of the wire, which is determined by the diameter. By quadrupling both, the resistance will increase by 4^2 = 16 times.
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.
You go to the NEC and look at the chart for developed length and the ambient temperature and the load factor and if it solid or stranded wire as stranded allows for more voltage
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.
Resistance is inversely related to the diameter of a wire. A larger diameter wire will have less resistance compared to a smaller diameter wire, assuming other factors like length and material remain constant. This is because a larger diameter wire provides more space for electrons to flow through, resulting in less resistance to the flow of current.
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.
