I'm hoping someone on here can give me a simple explanation of what a TRIAC does.
To give this request some context, I'm an embedded systems software engineer, so I interface with hardware, but I have no formal training in it. I was looking over a schematic for work and I saw a bunch of TRIACs being placed, but I am not familiar with this. I read the Wiki, but it's a bit much for me.
Can some one give me a basic example of what a TRIAC does and why you'd need them?
EX. I know a resistor, resists the flow of electricity
I know that a capacitor stores electric charge
I know diode's allow the flow of current in only one direction.
So like these basic concepts, can someone explain a TRIAC to me? Thanks.
