Electrical Engineering: Basic Concepts (7 of 7) Passive vs Active Elements

In this video I will explain the basic concepts of power in a circuit.

First video in this series can be seen at:

Thanks! This guy knows how the brain learns. You can not build something from nothing, and this serie provide a clear understanding on the most important concepts, while ignore the more advanced details, that you only can learn in the later learning journey. I wish my university knew this and didn't tried to cover as much as possible in the shortest time possible.

I wish you were my actual Professor. Best lecture I've ever watched in my many years of schooling

[simba]

Excellent bite sized lessons & very clearly explained ... Thank You.

[marbrydav]

I'm always relieved to find an explanation I need in one of your videos. You are truly broadening the availability of knowledge to the world with your convenient videos.Thank you Michel,

You learn more from him is 5 minutes than you do in an 1hr uni lecture lol

Question : Is this symbol also used for dc voltage source ?

Thank you for all your great videos and detailed explanations.

[itrstt]

I have been finding numerous references to transistors, vaccum tubes, relays, etc as active devices, stating an active device is such that controls electricity by means of an electric signal. On what i saw in your video the concept of active device doesn't seem to match, or am i perceiving it wrong? What do you say about it?

*The circle with the + - inside can also mean DC current source (like a battery for example), the symbol is not only used for AC*

Thank you for the video

[Alomani]

, ,,, nice and clear explanation
what about IC components .. it is active also

thanks

[MohammadkazimHalimy]

give some examples of dependent sources please

[sandlertossone]

Can you do some circuits with controlled sources in them please?

[jeffsam]

the second independent voltage source which theres a + and - inside the circle is not a AC voltage source as you describes? at 3:51 . I think thats a constant DC voltage source. correct me if im wrong

[joesam]

Wouldn't capacitors be considered ideal dependent source due to their ability to store energy?

[CaptainCalculus]

Hi, what do you mean by "ideal" source?

[jojojorisjhjosef]

So a transistor is active? and how about relay switches? or switches in general?
