Review of Scientific Instruments, 1946
The use of potentiometers in automatic electrical computing devices has necessitated a great improvement in commercial wire wound potentiometers in order to meet exacting requirements. For example, the use of ``end resistors'' has made it necessary to hold both the over-all resistance and the resistance gradient to close tolerances.

Reducing Potentiometer Loading Error
Review of Scientific Instruments, 1947In the practical application of potentiometers to electrical computer circuits, loading errors are invariably present. Where linear outputs are required the loading errors can usually be held within reasonable limits by careful proportioning of constants and by working on the most favorable part of the characteristic curve.

A Single-Molecule Potentiometer
Nano Letters, 2011Controlling electron transport through a single-molecule device is key to the realization of nanoscale electronic components. A design requirement for single molecule electrical devices is that the molecule must be both structurally and electrically connected to the metallic electrodes.

The Physics Teacher, 2005
The word potentiometer originally meant a device for measuring electric potential differences. Later, it also was applied to a tapped resistance used as a voltage divider. Although the measuring instrument is no longer used in undergraduate labs, it is the only truly perfect voltmeter, drawing no current and thus appearing to have an infinite impedance.

The High-Voltage Potentiometer
Transactions of the American Institute of Electrical Engineers, 1916The author describes a high-voltage potentiometer which may be made at reasonable expense consisting of a water resistance potential distributor and a sparking probe potential difference detector. The water resistance consists of a column of water moving slowly through an ample length of garden hose, and tapping in points through which to connect the ...

Proceedings of the Indian Academy of Sciences - Section A, 1934
The usual thermionic valve circuits for amplifying the small measuring current in potentiometric methods cause serious errors due to the appreciable grid current present in valves having high mutual conductance. On the other hand, the use of electrometer valve is attended with lack of sensitiveness. A d.c.

Electrical Engineering, 1934
A rectangular coordinate potentiometer circuit is described in this paper, the chief features of which are the elimination of the usual phase shifting transformer and the slide-wire type of potentiometer resistor. Although not yet available in commercial form this potentiometer has been in use in the laboratory for several years with good results ...
