GGGarden 10pcs Rotary B-Type 1K-220K Ohm Linear Potentiometer Assortment Kit 1/2W

welcome all to lecture series of subject mechatronics let us see working principle of potentiometers the potentiometer is one of the most commonly used device for measuring the displacement of the body the potentiometer is the electrical type of transducer or sensor and it is of resistive type because it works on the principle of change of resistance of the wire with its length potentiometer convert rotary or linear displacement to a voltage the resistance of the wire is directly proportional to the length of the wire thus is the length of the wire changes the resistance of the wire also changes potentiometer available as a rotary and linear potentiometer that can be used to measure angular position and linear position respectively potentiometer construction potentiometers consists of a resistive element a sliding contact or called as wiper that moves along the element making good elect
