**Description:**Potentiometer Experiment Class 12 , comparing the EMF of two primary cells given by using potentiometer and thus then to also find out its internal resistance.Determine internal resistance of a cell using potentiometer.To compare the EMF of two given primary cells using potentiometerWhat is potentiometer ? It is an instrument for finding out the resistance or EMF of an unknown cell , Leclanché cell by finding out the balance point using a jockey . The video will help you to lean how to calculate the balance point with potentiometer and unknown resistance or the EMF. To compare emf of two cells using potentiometerIt will be helpful for students studying for class 12th Board practical experiments in the time of January and February or March .For all Boards CBSE / ICSE / junior college / FYJC / state boards etcIf this helped, Please make a donation of anything above Rs 10 here : http://bit.ly/CBSE-Practicals :)Chemistry :-https://www.youtube.com/playlist?listPLQWMQxs-pAqmDJGEEKNnTbe1rdZiyUWofBio:- https://www.youtube.com/playlist?listPLQWMQxs-pAqll1xEx8d4Pnyp6FCWanzUKSection A:-1.
