how do you increase the drop of potiential per unit length of a potientometre wire?

							
Dear student,

A  potentiometer is an adjustable electro-mechanical transducer. The user  can adjust a potentiometer freely; the adjustments made change the  resistance over a circuit. As part of a circuit the potentiometer, or  pot, can have a countless number of functions. The most basic pot  consists of a tunable shaft, the casing housing the components of the  pot and three terminals for wiring. Usually physically operated with an  attached knob, two common uses for pots are as a volume control on a  stereo system or musical instrument, or as a variable resistor  controlling the speed of a motor or even the temperature of an oven.
