Feature:1. [50Pcs and 10 Type] This potentiometer kit has 50pcs in total and 10 types such as 500 1K 2K 5K 10K 20K 50K 100K 200K 1M Ohm, and each type has 5pcs.2. [Working Principle] The potentiometers' main working principle is to change the contact area or electric field distribution of conductive material in the material by rotating the knob, so as to change the resistance value.3. [Rotating Knob] Potentiometer is an electronic component that can change the value of a resistance, usually consisting of a rotatable knob and two endpoints, capable of varying the resistance between the two endpoints, thus changing the voltage or current of a circuit.4. [Adjustable Resistor] All of these potentiometers' resistors are adjustable, so you get this set, and you have a huge range of potential.5. [Divider and Controller] Potentiometer not only has adjustable resistor, but also voltage divider, volume controller and so on.Specification:Item Type: PotentiometerMaterial: PlasticColor: BlueUse: Widely used in a variety of electronic equipment, such as radio, TV, computer, etc..Package List:5 x 500 Ohm Potentiometer5 x 1K Ohm Potentiometer5 x 2K Ohm Potentiometer5 x 5K Ohm Potentiometer5 x 10K Ohm Potentiometer5 x 20K Ohm Potentiometer5 x 50K Ohm Potentiometer5 x 100K Ohm Potentiometer5 x 200K Ohm Potentiometer5 x 1M Ohm Potentiometer1 x Storage Box
