Trimpot is a high accuracy variable resistor and pcb mountable with 3 terminal pins. The voltage between the terminal varies as the trimpot is rotated.
For higher adjustment resolutions, multi-turn trimpots are used. The amount of turns varies between roughly 5-25, but 5, 12 or 25 turns are quite common. They are often constructed using a worm-gear (rotary track) or lead screw (linear track) mechanism to achieve the high resolution. Because of their more complex construction and manufacturing, they are more costly than single turn preset resistors. The lead screw packages can have a higher power rating because of their increased surface area.
The Variable resistors are used for variating voltage as per the need in a circuit. The outer two pins are connected to Vcc and 0V, and center pin outputs a variable volatge between 0v and Vcc as the rotary cermet is rotated.
