Nettet6. apr. 2024 · Current Density Example. Now that you are aware of the formula for calculation, take a look at the example below to get a clearer idea. Example – A 10mm 2 of copper wire conducts a current flow of 2mA. Determine this current density using the current density formula. Solution – In this example, current (I) = 2 x 10-3 . A = 10 x 10 … In electromagnetism, current density is the amount of charge per unit time that flows through a unit area of a chosen cross section. The current density vector is defined as a vector whose magnitude is the electric current per cross-sectional area at a given point in space, its direction being that of the motion of the positive charges at this point. In SI base units, the electric current density is m…
