Hey all,
I'm super new to electronics and had no clue what transistors were before reading through the "Semiconductor" section in e-book. It was very informative, but I still have some questions.
Isn't the function of a transistor the same as a relay? They both switch/amplify electronic signals. There are obviously important differences with respect to maintenance, how long the part will last, and how quickly the switch occurs, but with respect to function, they do the same exact thing, correct?
And if this is correct, then why do solid state relays involve so many components, that is, the LED, the TRIAC, etc.? Why not just use a transistor?
Answers would great, and direction to further reading would also be splendid!
