Principle
of
operation
The
principle of a potentiometer
is that the potential dropped across a segment of a wire of uniform cross-section carrying a constant current is directly proportional to its length. The
potentiometer
is a simple device used to measure the electrical potentials(or compare the e.m.f of a cell).
