Heya!
Potentiometer:
It is a electric device which is use to measure potential diffrence and emf accurately
Principle:
When a constant direct current is passed through a wire of uniform cross section them the potential drop on any portion of the wire is directly proportional to the length of that portion.
it means,
p.d is directly prop. to the balancing length.
