Did you know?
WebThe total electric current ( I) can be related to the current density ( J) by summing up (or integrating) the current density over the area where charge is flowing: [Equation 1] As a simple example, assume the current density is uniform (equal density) across the cross section of a wire with radius r =10 cm. Suppose that the total current flow ... WebElectric current is defined as the rate at which charge flows through a surface (the cross section of a wire, for example). Despite referring to many different things, the word …
