Consider a hypothetical closed Gaussian surface lying completely inside a

**conductor**, as at the left in Fig. 1.12. Since the electric field at every point on thissurface is zero, it can enclose no net charge. As this hypothetical surface can be

induction are in general negative, though in some cases they are zero.

If the isolated

**conductor**has a positive charge and hence a positive potential, anegative charge will be induced on the other

**conductor**. Hence the coefficients ofinduction are in general negative, though in some cases they are zero.
