Latelly I have found this:

"The primary use of a gyrator is to simulate an inductive element in a small
electronic circuit or integrated circuit. Before the invention of the
transistor, coils of wire with large inductance might be used in electronic
filters. A real inductor can be replaced by a much smaller assembly
containing a capacitor, operational amplifiers or transistors, and
resistors. This is especially useful in integrated circuit technology."

When the Gas Analogy substitute the Hydraulic Analogy (EM)?

Right. Andro, now THERE is a reliable source of information! I saw on
PBS that they found a fossil of one of Andro's ancestors.

L is the spring! You can tell because the symbol for and inductor
LOOKS like a spring! :-)

Truth is that L can be EITHER the mass or the spring depending upon
the given analogy you coose to use. Andro is clueless.

And your idea is that capacitors are inductors? You sound like Andro.
Next you'll be trying to tell us you found out about capacitive
transformers.

Maybe when someone shows that the Gas analogy better fits reality.

Marx did it in 1924. See: http://en.wikipedia.org/wiki/Marx_generator

In the electronic devices are only such transformers.

See the new topic: "Are antennas simmilar to the Kundt's tube?"
