black boxes

our sir asked this in the class
we are given with two black boxes one with a current source and other witha voltage source how do we distinguish them.... no terminals are provided
 

Re: black boxes

A.Anand Srinivasan,
I'm confused by the statement "No terminals are provided". Does this mean that the the black box has neither inputs nor outputs?
Regards,
Kral
 

black boxes

well if no terminals provided then we should shake the boxes
 

Re: black boxes

Yeah whats up with the "No terminals" thing. In that case the black box is just that simply a box, not quite usefull.

Did you perhaps mean that no extra terminals are supplied thus only the in and out ports are fitted on the box?

Cheers
