A box is not the best condenser.

You should use the Leyden jar.

How about a nice modern compact capacitor?

It should be with the low leakage. The Leyden jar has a thick insulation.
And,

"Any type of capacitor may develop excessive leakage if the capacitor is
subjected to excessive applied voltage or high-voltage spikes."

..It was known in Marconi time:
"It is now perfectly well known that a condenser, if large enough, does not
prevent the passage of high frequency oscillations, and therefore in these
cases
the earth is for all practical purposes connected to the antennae." (Marconi
1909).

In reality the real condenser conducts (electrons are flowing) the DC but do
not AC.
In the teaching program is opposite.

What an utter idiot.

Who wants to try to explain to this babbling idiot that the impedance of
a capacitor is 1 / ( 2 X pi X f X C) which means if f is zero (DC) the
impedance is infinite and there is no conduction (in an ideal capacitor).

You and teachers live in the ideal world where are the ideal capacitors.

Leyden jar has insulator made of glass.
It is possible to make it with insulator "made" of the air.

What will be leakage in such case?

Errr ... if your computer used capacitors with air dielectric then I doubt
we'd hear from you again.

If it helps you, capacitors pass AC and block DC.

Each insulator is a weak conductor.
At DC and pulse current electrons are flowing through the insulator
(leakage).
At AC not.

At AC the charging/discharging take place. The electrons flow into plate and
come back.

Charging current and discharging current do not pass or by-pas the
capacitors.

An insulator is ... an insulator. No leakage. If an insulator is not
insulating then you'd better handle your mains leads with care.

As usual, a pile of babbling nonsense.

I have a new capacitor design that uses clam chowder as the dielectric.
Interested?

I have a special oil extracted from the fat cells of rattlesnakes that
cures all cancers. Please send check for $500 for one pint.

This oil also provides artificial earth ground for all antennas.
