Thyristors,SCR,Diac,Triac,UJT theory

[akg]

sorta of i mean what do they do different than regular components?

Do they do something different to the current/phase/voltage?

I'm not sure what they do really ?

Ans the following
u have a water pipe line with a valve.
when u open and close the valve.
what happens to
flow of water , color of water , pressure of water ?

have a water pipe line with a valve.
when u open and close the valve.
what happens to

flow of water? its cuts off the water or changes the flow or puts opposition
to the water flow

color of water? changes the phase?
what u mean by the color of the water? what is the color?


pressure of water ? Pressure=voltage different voltage drops?

A Triac with a Diac feeding its gate is used in mains light dimmers and speed controls for power tools. They use a pot and capacitor to make a phase-shifted delay to turn on the triac early or late in each half-cycle of the mains voltage. Each time the mains voltage passes through zero volts, the load current drops to less than the holding current and it turns off. The phase-shift/delay parts turn it on in the next mains half-cycle.

You can learn about them if you want to make a light dimmer but they aren't used with guitars nor with audio.
