In the Potentiometer experiment, in
order to obtain the linear relation in
the calibration the following has to
be satisfied:
a. the emf of the power can vary
during the experiment but the
wire must be Ohmic, uniform,
and have a fixed length.
b. the wire must be Ohmic and
uniform and have a fixed
length but the current in it
does not have to be fixed
during the experiment.
c. the emf of the power supply
must be kept constant during
the experiment and the wire
must be Ohmic.
d. the emf of the power supply
can vary during the
experiment but the wire must
be Ohmic and uniform.
e. The potential difference
across the wire cannot
depend on the resistivity of
the wire.
