Electric potentials and field lines for uniformly-charged tube and cylinder expressed by Appell's hypergeometric function and integration of
Daisuke A. Takahashi
The closed-form expressions of electric potentials and field lines for a uniformly-charged tube and cylinder are presented using elliptic integrals and Appell's hypergeometric func…
