Hi, why transitors have 3 legs?

Why not 2 legs like everybody else? Thank you so mugs


Wilma,

I have three legs, one is just shorter then the other two.

Same with transistors, the short one controls the other two.

Those are actually just fuses.

You can fix pretty near anything by replacing the blown three-legged fuses.

That was a pretty base observation.

A two legged transistor could be a collector's item.

Ouch! that would hurt.... I beta just keep my mouth shut.

You are showing your bias.

Sometimes they are too inebriated and then they would fall over on just two legs :-)

That's a great teaching aid.

Thanks

They even fall over when uninebriated if they have only two legs. Think of a milking stool.

Not if you bend the leads so each leg has a "foot" :-)

I thought the short leg had no conscience?

Maybe it's meant as political control. Then it doesn't need a conscience :-)

Lets us not forget the negative voltage effect that will give you a pulse generator with only 2 leads of a NPN.

Of course, this discovery led to the tunnel diode.

And also, the photo transistor.

Of course a political control needs a conscience - it needs to know when what it does is going to upset some non-politicians. It's just that politicians seem to be able to ignore their consciences from time to time.
