Bessel functions for A-C. problems

Tables of Bessel functions of zero and higher orders are given for use in problems of skin effect and proximity effect in conductors carrying alternating currents. Formulas for deriving numerical values of the functions are given in the form of series for large and for small values of the argument. The series are complete with their general terms. The application of the tables to the calculation of the skin effect resistance ratio of an isolated tubular conductor is described and an example is given.
