Electrolytic capacitors are polarized capacitors whose anode (+) is made of a metal that forms an insulating oxide layer through anodization. This oxide layer acts as the dielectric of the electrolytic capacitor. A non-solid or solid electrolyte covers the surface of this oxide layer, serving in principle as the second electrode (cathode) (-) of the capacitor. Electrolytic capacitors are typically used most in applications such as audio amplifiers of all types (hi-fi to mobile phones) and in power supply circuits

Preset 10K Ω (ohm) (Variable Resistor) Cermet preset is a compact variable resistor and pcb mountable with 3 terminal pins. The voltage between the terminals varies as the preset is rotated. 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 voltage between 0v and Vcc as the rotary cermet is rotated.
