You can start with a diagram. It is mandatory here to show some efforts on your own.curiosity colour said:
I think it's should look like this, with the wire wound closely together( please excuse my horrible drawing).cnh1995 said:
The resistivity of a wire that is wound close on a cylinder is determined by the material of the wire, the diameter of the wire, and the length of the wire. It is a measure of how much the wire resists the flow of electric current.
The diameter of the wire has a direct impact on the resistivity. A smaller diameter wire will have a higher resistivity compared to a wire with a larger diameter. This is because a smaller diameter wire has less space for the electric current to flow through, causing it to encounter more resistance.
The longer the wire, the higher the resistivity. This is because a longer wire has more atoms and particles for the electric current to pass through, resulting in more resistance. Therefore, a shorter wire will have a lower resistivity compared to a longer wire.
Yes, the material of the wire plays a significant role in its resistivity when wound close on a cylinder. Different materials have different resistivities, and some materials, such as copper, have lower resistivities compared to others, such as steel. This is due to differences in atomic structure and conductivity of the material.
The resistivity of a wire that is wound close on a cylinder is measured using an Ohmmeter. This device measures the resistance of the wire and can calculate the resistivity using the wire's dimensions. The resistivity of the wire can also be calculated using the formula ρ = RA/L, where ρ is the resistivity, R is the resistance, A is the cross-sectional area of the wire, and L is the length of the wire.
