Question

State whether the following statement is true or false:

The basic principle of the potentiometer is that the potential drop across any section of the wire will be directly proportional to the length of the wire.

Accepted Answer

The given statement is true.Concept: In this question, we need to discuss the principle behind the working of Potentiometer. So basically, a potentiometer is a long piece of uniform wire having cells connected to it. In actual, potentiometer wire is cut into several pieces and placed side by side having their ends connected to each other with a metal strip. The current that flows is then varied by a rheostat which is also called variable resistance that is connected in the circuit. The potential difference through any two points in the circuit will be the amount of work done from bringing a charge from the first point to the second point.The potentiometer helps in measuring unknown voltage by comparing it to a voltage which is known. Through this we can also determine EMF and internal resistance of cells by the help of comparison.The basic working principle of a potentiometer is that the potential drop across a section will be directly proportional to the length of the wire, given that the cross section area is uniform and carries a uniform current flow throughout.Hence, the given statement is true.
