Semi Conductor, FET or Transistor.

A salesman telling us about transistors but what is wrong with this crap?
It seemed odd. Please fill us in.
The guy had that "yeah, science is difficult, but if I'm funky, cool and good looking enough you'll get it" thing going on.
Transistor have Base, Emitter,Collector not Drain, Gate, Source, wally man.
You appear to be attempting to counter him with knowledge and expertise.
No no no Colin.
Get a trendy haircut and a californian drawl, and then attend a media training course, and then, maybe then, we'll talk about "transistor "base"".
I like Mosfets - they self protect themselves to some degree (secondary breakdown).
