Answer:
a potential gradient is the local rate of change of the potential with respect to displacement, i.e. spatial derivative, or gradient. This quantity frequently occurs in equations of physical processes because it leads to some form of flux.
it's measured by an electric field mill.
As the electrode is exposed to the electric field, a charge is induced on the electrode, the magnitude of which is proportional to the field.
