Charge density - Wikipedia

In electromagnetism, charge density is the amount of electric charge per unit length, surface area, or volume. Volume charge density (symbolized by the Greek letter ρ) is the quantity of charge per unit volume, measured in the SI system in coulombs per cubic meter (C⋅m −3), at any point in a volume. Surface charge density (σ) is the quantity of charge per unit area, measured in coulombs ...

Volume of a Sphere Calculator 📐

Example: find the volume of a sphere. Only a single measurement needs to be known in order to compute the volume of a sphere and that is its diameter. For example, if the diameter is known to be 20 feet, then calculate the volume by using the first formula above to get 4/3 x 3.14159 x (20/2) 3 = 4.1866 x 1000 = 4188.79 ft 3 (cubic feet).

Understanding Volume Resistivity Measurements

Resistivity of copper is about 1.68 x 10^-6 ohm.cm For a layer R (sheet) x t (cm) = Resistivity. For thickness of 16 microns. t=16 x 10^-4. R (sheet) = 1.05 x 10^-3 = 1.05 mohm/square. So, for a copper layer that is 16 microns or thinner, the RM Series can be used.
