However, for some applications higher precision and ccrompton are needed, requiring changes in design features. Potentiometer Working Principle of Potentiometer The galvanometer circuit includes a set of compensating resistors R 1R 2. This provides a means of standard cell balance resistance to suit the emf value potentioemter the particular standard cell used. These EMFs may be of the order of one to several microvolts and are difficult to locate and control. The circuit of a single potentiometer may be modified in a simple way potentioometer add a second range, which is usually by a second factor, such as 0. DC Crompton’s Potentiometer or Laboratory Type Potentiometerĭuo range type potentiometer. If you have questions, then you can email me palakalaamarnath gmail. There is one dial switch with fifteen steps, each having a precision resistor. Also, a separate standard cell dial permits the operator to check the standard cell balance crkmpton any time during the cromptob of measurement without disturbing the potentiometer setting. We take into account the latest trends and standards set by our domain and offer suitable range of products. The long slide wire is awkward, and even for the length shown cannot be read to a very great degree of precision. The above requirement means that the voltage E ac in above figure remains the same for both positions of range switch S.Ĭall Send a quick message. With the protective resistance in the circuit, the potentiometer is balanced by means of the main dial and the slide wire. In this ootentiometer, only one or two main dials, consisting of decade resistance boxes, are used. Potemtiometer DC Crompton’s Potentiometer or Laboratory Type Potentiometer The following steps are used when making measurements with the above potentiometer: This completes the standardisation process for the potentiometer. Find more suppliers in Faridabad Carbon Potentiometer in Faridabad. The slide-wire type of potentiometer described in the previous article is not a practical form of construction. Construction and Working of basic slide wire dc Potentiometers. The below figure shows the schematic diagram of a duo-range two range potentiometer. Direct reading type, improved from with standardizing coil consisting of cromptkn coils and a circular slide wire The scale is divided into parts with potential drop compton mill volts Fine and coarse rheostats are provided for adjusting the slide wire current Range 0.

This potentiometer is supplied with a self standardization circuit built in, which renders You can download this article as pdf, ppt. The negative battery terminals are connected together and positive battery terminals are also connected together through a galvanometer as shown in the figure below.

The dial settings are kept exactly the same as in the original standardisation process. That means, emf of the standard cell is just balanced by the voltage appearing in the resistor across point A and B. The moving arm of middle dial carries two arms spaced two studs apart.
