Resistance between parallel wires in an insulator?

In summary, resistance between parallel wires in an insulator is the opposition to the flow of electric current in an insulating material when two or more wires are placed close to each other. It can be calculated using the formula R = (ρ x L) / A, and is affected by factors such as the distance between wires, type and thickness of the insulating material, and temperature. Knowing the resistance between parallel wires is important in designing and maintaining safe electrical circuits.

Hi all,

New here...I was wondering if anyone knows a formula to calculate the (insulation) resistance between two parallel conductors buried in an insulator. For example say 2 copper pins of 1mm diameter spaced 2mm apart over a 20mm length in a plastic (ptfe). The numbers/material are not specific to what I want to do just for example purposes.

Any help would be great as I've seen stuff for concentric cylinders but nothing for parallel conductors.

Would it be the same diffusion equation as for heat flow?
 

1. What is resistance between parallel wires in an insulator?

Resistance between parallel wires in an insulator refers to the opposition of the flow of electric current in an insulating material when two or more wires are placed close to each other.

2. How is resistance between parallel wires in an insulator calculated?

The resistance between parallel wires in an insulator can be calculated using the formula R = (ρ x L) / A, where ρ is the resistivity of the insulating material, L is the length of the wires, and A is the cross-sectional area of the wires.

3. What factors affect the resistance between parallel wires in an insulator?

The resistance between parallel wires in an insulator is affected by the distance between the wires, the type and thickness of the insulating material, and the temperature.

4. How does the distance between parallel wires affect the resistance?

The closer the wires are to each other, the lower the resistance will be as there is less insulating material between them. Conversely, increasing the distance between the wires will result in higher resistance.

5. Why is resistance between parallel wires in an insulator important?

Understanding the resistance between parallel wires in an insulator is important in designing and maintaining electrical circuits. It helps determine the amount of current that can flow through the wires without overheating them and causing potential hazards.
