E 4. 1 Introduction to Potentiometer A potentiometer is an electrical instrument used for measuring the potential difference (voltage) or for comparing the electromotive force (emf) of two cells with high precision. It is commonly used in various electrical and electronic devices and in physics and engineering experiments. Unlike a simple voltmeter, the potentiometer provides an accurate way to determine the potential difference across a component by balancing it against a known reference voltage. txt) or read online for free. In an NCERT Class 12 Physics context, a potentiometer is often taught as part of practical experiments studying electrical In Class 12 Physics, Chapter 3 delves into Current Electricity, and Topic 3. Potentiometers are passive components of the electric circuit that work on the principle of changing APPARATUS AND MATERIAL REQUIRED Potentiometer, Leclanche cell or dry cell, an ammeter, one resistance box (R 1) (about 0-50 Ω), 3 one way plug keys, galvanometer, a BOX high resistance box (R BOX 2) (about 0-10 kΩ), a low resistance rheostat of about 20 Ω, jockey, lead accumulator and connecting wires. A potentiometer consists of a uniform wire AB of low temperature coefficient of resistance stretched over a uniform wooden scale Fig. Show that currents are unaltered. Table of APPARATUS AND MATERIAL REQUIRED A wire of unknown resistance (~10Ω), battery eliminator or an accumulator (0 to 3V) or two dry cells (1. The CBSE Class 12 notes consist of chapter-wise notes and NCERT Solutions to prepare for the CBSE Class 12 Board exam. Potentiometer is a three terminal resistor used for measuring the unknown voltage by comparing it with the known voltage. Now we will study about the Potentiometer Working Principle,Uses, pros & Learn the potentiometer working principle, construction, formula, and uses with solved examples. 7 in the NCERT Text Book for Class XII. 5 V each), voltmeter (0-5 V), milliammeter (0 – 500 mA), rheostat, plug key, connecting wires and a piece of sand paper. 1(a). Do this for circuit of Example 3. It is used to compare the electromotive force of two cells, and to measure the potential difference between two points of a given circuit and the internal resistance of a cell.
