How much electric surcharge fits on … a “white dwarf” star?

The question how much surplus of electric charge ("surcharge") fits on an object is generally very difficult to answer. Here it shown that easy answer when the a \emph{failed white dwarf} star (a brown dwarf in its ground state) made protons and electrons: Given number protons, many electrons can there be? Surprisingly, (in form: as few $\mathfrak{A}$ $\mathfrak{B}$) independent speed light $c$ Planck quantum $h$, even stabilized against collapse by relativistic mechanics.
