Potentiometer Problems Jee at Angela Lewandowski blog

Potentiometer Problems Jee. Potentiometer — collection of solved problems. The working principle depends on the potential across any portion of the wire. A potentiometer made from homogenous resistance wire of length l and resistance rl = al is used to changed voltage at an. An ideal battery of 4 v and resistance r are connected in series in the primary circuit of a potentiometer of length 1 m and resistance 5ω. In a potentiometer experiment, it is found that no current passes through the galvanometer when the terminals of the cell are connected across. For $$r=10 \omega$$, the balance point is observed at $$l=500. The potentiometer is a device which does not draw current from the given circuit and still measures the potential. A potentiometer wire of length 300 cm is connected in series with a resistance 780 ω and a standard cell of emf 4v. To measure the internal resistance of a battery, potentiometer is used. This circuit is assumed to be a secondary circuit.
