As we know that potential difference is the amount of work done in bringing a charge from one point to another. When there is potential difference in a circuit, the current flows through the circuit. The Unit of Potential Difference is measured in Volts.

This project provides students with the tools and activities to learn the properties, principles of operation, and interface theory of … WebIn analytical chemistry, potentiometric titration is a technique similar to direct titration of a redox reaction. It is a useful means of characterizing an acid. No indicator is used; instead …
WebNow, let’s understand the theory on how to find the internal resistance of a cell using a potentiometer followed by the experiment on the determination of potential difference using a potentiometer. Theory: We know that a potentiometer is used to determine the internal resistance of a cell. Besides this, we will have a determination of ... WebTheory. The potentiometer is a device used to measure the internal resistance of a cell and is used to compare the e.m.f. of two cells and the potential difference across a resistor. The relation between potential difference, emf, and internal resistance of a cell is given by.
WebA potentiometer basically measures the potential difference between two points. Determination of Internal Resistance of a Cell Application of potentiometer A cell of emf E whose internal resistance r is to be determined is connected in the potentiometer circuit.
