Potentiometer formula class 12
Web4 Apr 2024 · The formula for calculating the cell's internal resistance is r = R ( L 1 − L 2) L 2 . Note: In a circuit, a potentiometer is used to measure the potential difference. It can also be used to calculate a cell's emf and compare two cells' EMFs. A potentiometer can also be used to calculate the cell's internal resistance. http://www.amrita.olabs.edu.in/?brch=6&cnt=1&sim=147&sub=1
