Can you use copper wire instead of eureka wire in finding its resistivity?
no
What other methods besides the water displacement method can you use to determine the density of a marble and a wire?
Water displacement, in and of itself, cannot be used to determine density. Density is defined as mass divided by volume. Water displacement determines only the volume part of density. Whatever method you use to determine volume, you still need to determine the mass of the item before you can calculate its density. That said, another way to determine the volume of an object is to measure its dimensions and apply the appropriate formula. A wire can be considered a cylinder. A very long and very thin cylinder, but a cylinder nonetheless. The formula for the volume of a cylinder is: V = lπr2 where l is the length of the cylinder, π is "pi", the ratio of a circle's circumference to its diamater, approximately 3.14159, and r is the radius of the cylinder, or half of its diameter. Simply use a ruler to measure the length of your wire. If it is bent, twisted, or kinked, you will need to straighten it out first. Instead of measuring the wire's radius, you should measure its diameter and divide by 2. Unless your wire is thick, it may be difficult to get an accurate measurement of its diameter, even in millimeter units. Instead, you might try cutting the wire into ten pieces and laying them all side by side, touching each other, then measure the total width of all then pieces, then divide by 20 to determine the radius of your wire. It is important that you use the same units for both length and radius of your wire. Once you have determined the length and radius of your wire, square the radius, then multiply it by 3.14159 (π), then multiply it by the length of the wire. That is your volume. If you measured your length and radius in millimeters, the volume will in cubic millimeters. A million cubic millimeters is equal to one liter, so if "liters" is the unit in the denominator of your density measurement, you will need to divide your "cubic millimeters" volume by 1,000,000 before computing density. A marble is a sphere. The volume of a sphere is determined by the formula: V = 4πr3/3 or V = πd3/6 where d is the diameter of the marble. To determine the diameter of your marble, place it on top of your ruler with the left side even with the zero mark, then measure where the right edge falls on your ruler. Again, this may not be very precise. Alternatively, you could make a mark on your marble, then place your marble on the ruler with the left edge at the zero mark and the mark in the exact center of the marble as viewed from above. Then roll the marble, one complete revolution, along the ruler, until the mark is again in the exact center, then measure where the left edge of the marble is again. This is the circumference of your marble. To determine its diameter, just divide by pi (3.14159). To determine the volume of your marble, multiply the diameter by itself, then by itself again (d x d x d, or d3), then multiply by pi (3.14159), then divide by six. This is the volume of your marble. If your diameter measurement was in millimeters, the volume will be in cubic millimeters.
How is the movement of electricity through air different from its movement through copper wire?
The Air is many molecules scattered all around and copper wire is molecules in a line and very condensed where air is not. Therefore copper wire is a better conducter
Can copper and alluminium wire of same length and diameter have same resistance?
For a single temperature, yes. The copper wire will have a much smaller cross-section than the iron wire. For multiple temperatures, no. Copper and iron have different temperature coefficients for resistivity.
What is able to be stretched into wire?
There are several metals able to be stretched into wire. In electrical wiring, copper or copper coated aluminium is commonly used. Steel is also able to be stretched into wire.
How much copper wire makes a pound?
That would depend on the thickness of the wire. Here is how you can calculate it: Look up the density of copper. Use this to find out how much volume you need. Reminder: mass = volume x density. Decide what diameter copper wire you want to use. Divide the diameter by 2 to get the radius. Use the formula for the volume of a cylinder. Insert the known volume and radius, and solve for the length. You may need some unit conversions. For example, if the density is given in pounds/cubic foot, and the diameter of the wire is given in inches, you would need to convert the radius from inches to feet. If the copper wire has plastic insulation, the calculation of course is different. You might also get data directly from data sheets, about the mass per unit length, for different wires.
How many atoms are in a 1cm of copper wire and who calculate this?
We need to know the diameter of the wire to calculate the volume and the mass. Number of atoms is: 2,58.1023.r2, where r is the radius of the wire.
Why does density happen?
Density doesn't happen. It's simply a derived metric, a math term. But in general, density is a measure of quantity per unit basis. Here are some examples: Q/U = kilograms of mass/volume in meters^3 = mass density Q/U = number of people/area containing them km^2 = population density Q/U = number of electrons in a wire/length of the wire meter = electron linear density NOTE: The unit bases were volume, area, and length. My point is that density can be specified by any one of those three bases.
Why is the density of copper wire more than the density of PVC?
copper is metal, density greater than water.PVC is synthetic organic, density less than water.
What is the mass of a wire?
depends on the kind of wire. Lead wire -- 11.5 g/cm3 gold wire -- 18 g/cm3 copper wire -- 8 g/cm3
Which element is used in place of copper in wire?
The most commonly used element other than copper used for electrical wire is aluminum: It is not quite as good a conductor of electricity per unit volume as copper, but is much less dense, so that it is a better of conductor per unit mass density, an advantage in some uses. If high electrical conductivity* is not needed, iron or its alloy steel is most commonly used because is cheap and has good mechanical properties. ______________ This does not mean that iron and steel are nonconductors!
Compare conductivity of iron copper and aluminum in terms of electricity.?
When compared by volume, copper is best, then aluminum and finally iron. When compared by weight, aluminum is better than copper. You have to compare by volume because aluminum is so much lighter than copper, an aluminum wire that weighed the same as a copper wire would be much bigger and harder to work with.
What are the elements in a copper wire?
If the copper wire really is pure copper then the only element in the copper wire is copper (Cu).
Why is wire better than copper wire on an electromagnet?
whty is copper wire not better than wire on a electromagnet whty is copper wire not better than wire on a electromagnet whty is copper wire not better than wire on a electromagnet whty is copper wire not better than wire on a electromagnet whty is copper wire not better than wire on a electromagnet
How do you calculate total weight of alluminum wires?
You have to multiply the density of aluminum on its volume. For wires the volume will be the cross section multiplied by the wire length.
