R = (density)(Length)/(Area) Unit of resistance is Ohms.
Adjust the compass to the given line segment then construct the circle.
Yes and each edge will be 7.93700526 units in length
The change in temperature is 973-21 = 952C The expansion over that range is 20.8 x 10 to the minus 6 per degree The change in length over 2 meters is 20.8E-06 x 952 x 2 = 0.0396 meters
You don't specify diameter. I am assuming it is the same. However, the larger the wire the lower the resistance. Temperature affects resistance. The hotter the wire, the higher the resistance. You also don't specify the layout of the wire. For example you could make a coil or choke with one wire.
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.
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.
A short thick copper wire at low temperature would have lower resistance compared to a long thin iron wire at high temperature. This is because resistance is inversely proportional to cross-sectional area and directly proportional to temperature and length of the wire. The short thick copper wire has a larger cross-sectional area, which results in lower resistance.
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.
The resistance of a conductor is affected by its length, cross-sectional area, material, and temperature. Longer conductors have higher resistance, while wider conductors have lower resistance. Different materials have different resistivities, influencing resistance. Temperature also affects resistance, usually increasing with higher temperatures.
Factors that affect resistance of electricity include the type of material the wire is made of (e.g. copper vs. aluminum), the length of the wire (longer wires have higher resistance), and the cross-sectional area of the wire (thicker wires have lower resistance). Temperature also affects resistance, with higher temperatures typically leading to higher resistance.
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.
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.
The four factors that determine the resistance of a material are resistivity (intrinsic property of the material), length (longer length increases resistance), cross-sectional area (smaller area increases resistance), and temperature (increases in temperature usually increase resistance). Examples could be copper with low resistivity, a longer wire having higher resistance, a thinner wire having higher resistance, and a material like a semiconductor having resistance affected by temperature changes.
The four factors affecting resistance are material, length, cross-sectional area, and temperature. Resistance increases with longer length and higher temperature, while it decreases with larger cross-sectional area. The material used also plays a role, with materials like copper having lower resistance compared to materials like steel.
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
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.
