it's not tau it's τ :P

The definition says the voltage in a capacitor equals the charge applied to the capacitor.
1amp aplied for 1 second into 1 faraday capacitor equal 1 volt...
what is restriction of amps than?
A 1henrie inductor will have 1amp flowing thru it if 1 volt is applied for 1 second...
What is the doubled pulse than?
In a resonant circuit the energy becomes all magnetic at one time and all eletcric at the other...
A diode can prevent a capacitor from discharge....

A diode can prevent a perfect capacitor fom discharge. Since there is no perfect capacitor, then?

to Ts,make a real water capacitor can solve that.

Volts and Amps are different units that are not directly interchangeable. You cannot say 1A = 1V in any context. It's like saying 1 lb/sq inch air pressure equals 1 cubic inch of air volume. It doesn't make sense because the two units are not interchangeable this way.

of course, but i'm not saying that.
i'm only saying that for a capacitor of 1 faraday to get 1 volt it must flow 1 coulomb of charge, if its done in one second 1 ampere will be the average current...
thats the definition...
same for henrie
what is one henrie?
is the inductance that will let 1 ampere of current to flow if 1 volt is applied for 1 second..
the voltage across a capacitor will equal the charge stored in this capacitor
the current flowing in a coil similarly equal the voltage charge aplied..

1A at how many volts? 0.1? 1? 1000V. Does it matter? The amount of charge still has to be dependant on the voltage doesn't it? Or are we assuming 1V as was stated in the previous sentence? I'm sorry, but its not very clear to me in context.

its the definition...
don-t confuse charge with voltage, charge stands for coulombs...
if you apply 1 volt to a 1 faraday capacitor the instant peak current depeds only on the resistance of the circuit. this will tell how fast a capacitor can charge or discharge...
if you apply 1 volt to a 0 resistance 1henrie inductor it will take one second to get 1 amp flowing
try on simulation... this is the definition of henrie and faraday
they are similar and exactly the oposite...
the difference is
at the capacitor only will flow 1 coulomb per volt per faraday and stuck there
at the inductor with 0 resistance the current just keep increasing evenly at constant voltage applied... if time allow it...
again at the capacitor the voltage increase constantly at constant current flow for example...

something that confuses me are the diffrence in charge and joules specifically:
electron charge (e) = 1.60E-19 C
electron volt (eV)= 1.60E-19 joule
-
simple is the energy that one electron would gain if cross a potential of 1 volt thats why its got the same numbers..
-

can you give me an explanation of a senerio if I have one 1,826volt electron with a potential diffrence of 11 volts, how many joules would that be?

Aside from that silly question... i just read this paragraph... something else i dont understand
"The charge of one electron might be used as a unit of electrical charge, since charges are created by displacement of electrons; but the charge of one electron is so small that it is impractical to use. The practical unit adopted for measuring charges is the COULOMB, named after the scientist Charles Coulomb. One coulomb is equal to the charge of 6,280,000,000,000,000,000 (six quintillion two hundred and eighty quadrillion) or (6.28 x 1018) electrons."
-
new guy... if we assume this 1,86ev is kinnetic energy than the sum dependes on the vector direction, if it will sum to the 11volts potential or subtract....
1 coulomb per second is 1 ampere.... so 6,28x10^18 x 1.6x10^-19 = 1 coulomb so coulomb is simply a measure of charge of a group of electrons good to work with, remember the charge of one electron is the smallest charge póssible....
and again 1 amper/hour is 3600 coulombs

remembering what stan said 5 amps big deal... 40? big deal
Definition
If the rate of change of current in a circuit is one ampere per second and the resulting electromotive force is one volt, then the inductance of the circuit is one henry. Other equivalent combinations of SI units are as follows[3]:

Definition
A farad is the charge in coulombs which a capacitor will accept for the potential across it to change 1 volt. A coulomb is 1 ampere second.
Equalities
A farad has the base SI representation of: s4 × A2 × m−2 × kg−1
It can further be expressed as:
