Answer 1

ĀNSWĒR ⏬⏬

⭕ POTENTIOMETER :

It is a three-terminal resistor with a sliding or rotating contact that forms an adjustable voltage divider. 

✨ PRINCIPAL :

⭐IT is that the potential dropped across a segment of a wire of uniform cross-section carrying a constant current is directly proportional to its length.

⭐ Between the end of the wire and any point along it will be a potential proportional to the length of wire to that point.
