摘要：
A method is proposed for calculating current density in a pair of coaxial conductors whose cross- section has the shape of annulus. The conductors are connected to a sinusoidal voltage source. The method is demonstrated using examples, including the calculation of current density in a cylindrical conductor connected to a sinusoidal voltage source. A similar problem is solved more than 100 years ago, where the wave equation is solved in terms of Bessel functions. This classical solution is analyzed critically.
