The thyristor is a four-layered, three terminal semiconductor device, with each layer consisting of alternately N-type or P-type material, for example P-N-P-N.n earlier gas filled tube device called a thyratron provided a similar electronic switching capability, where a small control voltage could switch a large current. It is from a combination of thyratron and  transistor  that the term thyristor is derived.
One device frequently used as a voltage-dividing component is the potentiometer, which is. a resistor with a movable element positioned by a manual knob or lever. The movable element, typically called a wiper, makes contact with a resistive strip of material (commonly called the.otentiometers: what they are, how they work and how to use them with Arduino.
