ВЭФ 12 (Astrad VEF 12 Project) - including a transistor tutorial

[Mark Hennessy]

Earlier I linked to The Art of Electronics, and specifically "Transistor Man". I have no idea if you've had a chance to look this up - it's a big download - so here's a grab of the image I wanted you to look at. It might help here.

   

As Mike says, you may wish to think of the collector-emitter junction as a resistor of sorts.

Therefore, everything we have done so far has been to set the collector current to 1mA.

The final step of the journey is to determine the collector voltage.

This again is just the application of Ohm's law. But, because I'm very fair, I'll mention that there is a trap that folk usually fall into at this stage. Only a small one, but useful from the learning point of view, so don't feel bad if it happens... So I'll say no more at this point - over to you: what is the collector voltage?

Don't be afraid - this is simpler than you think. Heck, you don't even need a calculator...
