I would like to know the name or an explanation to what the colored "grey" objects in these example circuits mean. This picture was taken directly out from a textbook that used it for references of dependent sources.

Sorry I'm new to this site. How do I move this thread to the homework section?

 

Hello,

I have moved the thread for you.

They merely represent the rest of the circuit that has to be there, but is unimportant to the behavior of the controlled source.

Right, but what do you call them? Is there a technical name for those grey objects?

 

Blobs?

Perhaps "black box"?

Or maybe "arbitrary circuit cloud"?

They are not defined. The whole point of them being there is to indicate something that you don't need to know about in order to understand what IS there.

 

I would venture "field devices."
