Mosfet and/or BJT current-voltage tutorial

I'm trying to understand mosfet and bjt's.

I'm wondering if anyone knows if a tutorial where the voltage changes in the case of a mosfet or the current changes in the case of the BJT result in changing of the current flowing through the S-Drain and E-Collector?

Im very visual :slight_smile:

I am sure you can find some instructional videos on YouTube.


I have found about 5. I'm just wondering if anyone knows of a particularly good one that maybe shows how when the voltage varies the current flow varies using a real Arduino setup.

Oh! Just found a good one without the Arduino part.

There quite a few Arduino related videos on YouTube.

You may also want to take a look at some of the C and C++ offerings also.


@Marciokoko, if you don’t already have it, you might benefit by downloading/installing LTSpice IV so that you can simulate simple circuits and see the results in graphical form.

Im not sure if my set up is right. What I would like to do is see how I can ramp up the voltage on V2 from 0-5V and see the change in current flow?
