Question
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 supply must be kept constant during the experiment and the wire
must be Ohmic.
O 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.
O c. The potential difference across the wire cannot depend on the resistivity of the wire.
O d. the emf of the power can vary during the experiment but the wire must be Ohmic,
uniform, and have a fixed length.
O e. the emf of the power supply can vary during the experiment but the wire must be
Ohmic and uniform.
