Potentiometer Balancing Length Formula at Douglas Reddy blog

Potentiometer Balancing Length Formula. Potentiometer works on the following principle: Cj is the balancing length l. The potential difference across cj is equal to irl where i is the current flowing through the wire and r is the resistance per unit length of the wire. With key k2 open, balance is obtained at length l1 (an1). The emf of the cell is directly proportional to the balancing length. If another cell of emf 2.5 v replaces the first cell,. In a potentiometer circuit, a cell of emf 1.5 v gives balance point at 36 cm length of wire. A potentiometer consists of a wire of length 400 cm and of resistance 10 $\rm \omega$. Then, ε = φ l1…(i) [where φ is the potential drop per unit length]. Since i and r are constants, ξ ∝ l. When a constant current is passed through a wire whose cross sectional area is uniform, then the potential drop or difference. It is connected to a cell of e.m.f 2 volt having.
