WebCBSE Class 12 Lab Manual for Chapter 4 2 To Compare The EMF of Two Given Primary Cells Using Potentiometer . The laboratory is important for making the study complete, especially for a subject like Science and Maths. CBSE has included the practicals in secondary class intending to make students familiarised with the basic tools and … WebPotentiometer A potentiometer consists of a uniform wire AB of low temperature … WebAccording to the Wheatstone-bridge principle, the resistance of length AB/resistance of length BC = R / X. Let l be the length of wire between A and B and then (100 – l) is the length of wire between B and C. Here, P = ρl / A. Since the wire has a uniform cross-section and ρ is constant. Its resistance is proportional to the length. lee frank south berwick
