Circuit Analysis -Transistor Tutorial - Common Emitter Circuit - Digital Inverter - Part 4

http://www.FreedomUniversity.TV. A series of videos on circuit analysis with applications to transistors. Transistors are important to know since these elements are a prelude to understanding how operational amplifiers work. Another example of the common emitter transistor configuration is discussed with application as a digital inverter. For questions on these and other videos, contact Professor Santiago at john@e-liteworks.com or visit the above website.

Thanks for the clarification. Dr J

What do you mean by program? Are you talking about the software screen recording? If that's the case, it's Camtasia. Dr J

@tonyisgrendel Thanks lot..

perfect, thanks

You can treat the whole wire as a resistor. Because all wires have resistance. and it can be abstractly considered a circuit with a voltage of 0v or with no voltage source at all.

BUUUUUUUUUUUT

Let's say you have that (connected) loop and you pass a strong magnet through the loop back and forth. A (small) current will flow through the wire. The current will not flow if the wire is not connected in a circle/loop.

You can probably model the current as a Dependent Current source.

What does Vcc represent again?

[darkknightgaury]

If you connect a cable in a circle it is not a electrical circuit. An electrical circuit as far as I know is a mathematical representation of a system. If you can somehow express the wire in a circle with circuit symbols then is a electrical circuit. I don't see how you would do that with just a wire. Maybe someone with more knowledge can help you on this one.
