To minimize the resistance of the connections and ensure negligible voltage drop across the joints.

Vedclass · Answer

(C) In a potentiometer, instead of using a single very long wire, multiple wires of $1 \,m$ length are connected in series using thick metallic strips.These thick metallic strips have a very low cross-sectional resistance compared to the potentiometer wire.By using thick strips, the resistance of the joints becomes negligible, ensuring that the potential drop occurs only across the potentiometer wire itself.This design allows for a compact arrangement while maintaining the accuracy of the potential gradient along the wire.
