Most wire or string is made with a circular cross section of some particular radius and diameter. The area of that cross section is the well known A = pi*R² which is colloquially pronounced as “pie ...

The volume of a cylinder is the area of the cross-section multiplied by the height. D button is used to convert a value in terms of π to a decimal value. To calculate the surface area of a cylinder: ...

When installing conductors of different sizes (or types of insulation) in a raceway, you can’t size the raceway based on Tables 1 through 12 in Annex C. You must instead follow this three-step process ...

A second experiment can be carried out to investigate experimentally how the resistance of a metallic conductor at constant temperature depends on the area of cross section. The above experiment is ...

There are times when we need to add conductors to an existing raceway. But do you know how do so without damaging either the existing or new conductors, or both? You ...
