Goal: Hone the relationship between E and V
Source: 283-475 Must V=0 if E=0?
True or false: it is possible to have the electric field be 0 at some
point in space and the electric potential be non-zero at that same
(1) Whichever answer students give, ask them to draw a charge
configuration which satisfies their answer. Often this is sufficient to
cause them to change their mind. If appropriate raise for discussion the
case of the interior of a uniformly charged spherical shell.
