I know transformers are magnetically coupled inductors,

and when an AC current is passed thru one inductor, it produces
alternating magnetic fields, which then induces current in the near by
inductor...(pls dont go into technical of it,with formulas and blah
blah blah.i have noticed a strange thing out here ppl miss the
question and start explaining the concept in detail...pls dont do
that)


I was wondering can the same thing be achieved by two capacitors
linked by electric fields??

is there such a concept in existence? links...

Sorry for the lame ascii..
but thats the only way i can explain

Capacitive coupling is real enough but requires an enormous voltage to be
effective, and that is simply not practical. In any real experiment you'd
find the voltage arcs over.

Perhaps the closest you'll get is a pair of radio transmitter and receiver
antennae. The voltage at the transmitter can be in kilovolts, but only
microvolts in the receiver. A broadcast FM radio transmitter can reach
about 60 miles. Of course if the signal is beamed using a dish it can reach
Saturn.

Not completely wrong. People have noticed that one can set up an
electrostatic analog to an electromagnetic situation. If you were to
scan the literature on network theory you would find many references
to capacitive transformers as theoretical devices useful in the
calculation of network solutions. They are just not practical devices
you can go buy at Radio Shack. Certain Piezo filters are about as
close as you can get to a practical capacitive transformer.

The nearest I can get to your suggestion is a capacitor ladder but that's
not quite the same....

Actually not the same at all.

I see what you are getting at now and yes it could be made to work.

Three capacitors in series also works.
