What is the maximum charge in Coulombs can be obtained in ionistor?

What is the maximum charge in coulombs can be obtained on the plates of ionistors like these: https://en.wikipedia.org/wiki/Supercapacitor ?

Hi
welcome to PF

ionistors

what on Earth is that ?
the link you supplied goes to capacitors, and in particular, super capacitors

Capacitors have their Farad rating printed on them

 

[ivanovenkoi]

Ionistor is the same as capacitors. I mean capacitors exactly. I need the maximum available charge in Coulombs, not in Farads. Because Farad measures not charge but electrical capacitance.

P.S. Sorry for my poor English, I am not english speaker.

Ionistors are capacitors in general. I need not Farad, because farad is electrical capacitance. I need charge in coulombs.

I need the maximum available charge in Coulombs, not in Farads.

Q=CV

So multiply the Capacitance in Farads by the Voltage in Volts, and you get the stored charge Q in Coulombs.

Q=CV

So multiply the Capacitance in Farads by the Voltage in Volts, and you get the stored charge Q in Coulombs.

So can it be 10000F × 5V = 50000 Coulombs for ecample? Or it's too much? I need digit order. Because I read that 1 coulomb is a very big charge. So 50000 is extremely big, isn't it?

10,000 Farads is a huge capacitor. Where are you finding something like that?

https://en.m.wikipedia.org/wiki/SupercapacitorHere I see in the table below supercapacitors 100..12000F, 2.2..3.3V
So 12000F*3.3V is almoustly 40000 Coulombs, isn't it?

Be sure to read the limitations of supercaps. What is the application? You are not going to dump all of that charge all at once out of a supercap...

What berkeman said is right.
If it is for a practical application beware of the maximum charge and discharge current for the specific capacitor you buy.
