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.
Potentiometers, more commonly known simply as pots, are a type of electrical component called a variable resistor. They usually function in conjunction with a knob; the user turns the knob, and this rotational motion is translated into a change in resistance in the electrical circuit.erminal 2 is the input of the potentiometer, meaning the output line from the circuit should connect to it. For example, on a guitar, this would be the wire leading away from the pickup. In an integrated amplifier, this would be the wire leading from the pre-amp stage.
