In physical wires that carry current, the majority of the current will actually travel very close to the the outer edge of the wire (in the same way that static charge deposited on a conductor will spread across its surface rather than its interior). One way to model the physical flow of charge through a cylindrical wire of radius R is with the following current density function: with Jo = 2.5 × 106A/m 2. Note that this is only true...
