Hi, why transitors have 3 legs?

Be careful, legg. Somebody might try to solder you down.

Hardly, since those are pointers to the logical fallacies you made.

There are no real questions, there are only silly statements you make up so you can provoke people into playing your game.

Twist the topic around? To electronics? Away from hen squabbling? The nerve!

I guess you don't use any PCB layout software.

It will be pretty busy today; gotta ship that first gradient pulser and Gerber a laser driver board. I suppose I should shower and get going. I like to let the traffic settle down a bit first.

What are you up to?

It depends on the situation. Since, as you say, "They are just words, and don't matter much.", in a setting like this, where it's obvious that "legs" is what's being used to describe the wires exiting a transistor's body, of course I would.

All true, but banal and hardly germane in the context of USENET.

Riveting reading though it is, would you ladies please conduct your cat fight elsewhere?

But this isn't the professional engineering community, it's USENET.

The topic started off as a little electronics troll, specifically about two-legged transistors. Now, you've twisted it around to where it's a harangue about terminology.

Feeling steady on your pins, boy?

A fact you have obviously forgotten, since you claim to have never heard of a transducer connection being referred to as a "leg".

You are a liar or an interloper in the industry. You decide which.

Were I your customer, it would matter a hell of a lot more if you actually knew the terms before you felt the need to hunt them up, just to "sound good". If I knew ahead of time that you were just a 'word shill', you would win no contracts from me.

You are the worst type of 'engineer', by far.

To say nothing of the possible tape and reel questions.

I don't care to, but thanks for asking. :-)

Leads, legs, pins, terminals, dohickies or whatever; the term used don't mean squat so long as clear communication is achieved.

Transducer leg? No, I don't think I've heard of a transducer connection being called a "leg."

Google "transistor leg." All the hits look like amateurs.

I never knew about cryogenic temperature and level sensors until I had to learn about them. What's wrong with learning new stuff? What's good about sounding ignorant?

Now, now... Take the high road. :-)

Thermocouples are often referred to as having legs. Also: http://www.google.com/patents?id=scckAAAAEBAJ&printsec=abstract&zoom=4#v=onepage&q&f=false
