Current amplifying vs. voltage amplifying.

[roly94]

Guys thanks tons for the help.You guys are the best.It is gettin' clearer.
Well I have thought this through and have come up with,perhaps,a more apparent and obvious analogue.One doesn't need to refer to configurations of open or closed loading situations with transistors I hope.Merely keeping things at the conceptual level by referring to this water analogue.Here is the more accurate analogue I think.Please,please correct me if I am wrong:
This system involves 4 water tanks altogether.Two 5 gallon carboys(office water tanks ala crystal springs,alhambra,etc.) have water flowing,i.e.,oscillating back and forth between them through a pipe.At time T=0 one tank is completely full the other empty.Once the valve is opened the water flows back and forth continually(hypothetically) with no resistance(resistance is not really necessary in this analogue).In the middle of this pipe there is a butterfly valve that swings on its hinges like a Dutch(saloon) door back and forth with the water flow past it.Instantaneously open all the way in one direction,then at a very small increment of time afterwards open all the way in the other direction.Graphically this butterfly valve generates a sine wave which is the input signal.
The butterfly valve is directly coupled via some mechanical linkage to another larger butterfly valve in another pipe which is between 2 humongous "city" water towers that also have water oscillating back and forth between them.The small butterfly valve CONTROLS the swinging back and forth of the large butterfly valve thus controlling the oscillation of the larger water tank water flow.The 2 large water tanks represent the power available from double ended rails.The small butterfly valve then to the extent that it is directly coupled and controls the larger butterfly valve replicates the carboy water pulses(input oscillation) with much more power available with the large water tanks,hence producing an "amplified" output.The small input butterfly valve is,in essence,then a transitor.It controls the power of the double ended rails,the larger water tanks.
Now here is what I hope is the crux of the matter in making this system more "voltage oriented" vis a vis "current oriented" or current amplifying.
If the input butterfly valve has a spring attached to it with a very high spring constant or stiffness it would take alot of pressure(voltage) to get the input butterfly valve to swing back and forth,hence,the input system here is more oriented toward the pressure of the carboy tanks or voltage.Only a large pressure can get the input butterfly valve to swing back and forth.
Now the opposite.If the spring constant on the input butterfly valve were very slight and a very low stiffness(hair trigger as it were) then it wouldn't take much pressure at all to operate this system.Just the slightest amount of current flow or ripple would dictate things and thus the output system,oscillation of larger tanks, is controlled by a more current oriented system of the input.Thus one could say here the larger tanks amplify the input current.
I profusely apologize for the long winded attempt here.
If this analogue is correct,though, I will have it locked up watertight and perhaps have a way to explain to my tube loving friends just exactly what it is that a tube does vis a vis a transistor(bipolar).Then I can move on to the 3 basic configurations of transistors and later even the parameters.Thanks tons again,Roland.

Hi,
Dope ? Guru? Wittgenstein; who the h*** is that?
I am alife and kicking! Clean as a whistle!

Hi Sonny,
Yes I am positive, absolutely sure.
Actually I live in the town of <B>GRO</B>ningen, in the Northern part of the Netherlands.
I couldn't not resist it.
All the best,

I want some of what this guy is smoking........ Or maybe he is poking fun at Grey's typical explanations? Please don't pick on Grey please.
