Good evening,
I have a simple question , how do I know and how many voltages should I charge a capacitor , I checked in YouTube and I did not understood why in some videos They added a resistor behind the capacitor, is it needed ? Which voltages should I charges how do it workS? Please explain about it , thank you very much have a good night

 

"competitor", "compositor" - those terms are not used in electronics.

Do you mean "capacitor" or "condenser"?

 

I meant capacitor, I use dictation to write lol

 

How many volts to charge a capacitor?

It depends on the circuit and the application.

Also, capacitors have a voltage rating. Do not exceed 80% of the voltage rating.
If the capacitor is rated at 16VDC, do not exceed 12V.

 

How do you know the it should not exceed 12v?
Because I want to know by myself those things , can you please explain?
The capacitors are a new thing for me

 

What do you plan to do with the capacitor?

 

Something very random I don’t really know lol, I just want to know how to charge it, if i have 6 capacitors of 2 volts connected in series, ill have 12 volts capacitor, how could I charge them?

 

Everything is dependent on aim of use. Probably 1 mA 12V power filter. Probably 1000 000 Amp 12V magnet supply, probably 10A 100 kV underwater blast device, probably laser HV supply, probably reserve power supply for grid interruptions etc etc. Every case it has different specifisms, thus, start with telling the aim.

 

Well im building a aluminum melting foundery, it will work on 220v 300w I’ll use the correct amount of solar panels, i want to connect it to the capacitos and the foundery to the inverter and the inverter to the capacitors , just to stabilize the voltages.
How can i make the capacitors be in charging from the panel?

 

300W/220V=1,5 Amps what translates in the 12V and 30Amps. Thus sucking from finger the cap battery will want to stabilize some 5 sec long interruption, we get the equivalent 12V load resistance R=U/i=12/36=0,3 Ohm As the C=tau/R means C=5/0,3=15 000 000 microfarads what smells for wagon full of supercaps. Thus, translate it back toward 220V side where R=220/1,5=150 Ohms and then C=5/150=30 000 microfarads what is damn much but at least realistic. Hope now You see the clue - cap in the low side is sensless.

 

It sounds like you are new to electronics. With that in mind, I would very strongly advise you to NOT proceed. You are dealing with lethal power levels there. It you must proceed, get some qualified help. This is not the thing a novice should be starting with. VERY dangerous!
Sorry if that answer does not please you, but I would be amiss if I did not warn you.

 

May only add Amen.

 

No, I may advice sth very simple but effective, put the low side the accumulator. Some ordinary personal car type, 50-70 Ah will serve well on those 30A. The 12-->220V by ordinary vehicle converter brick, that is some 20-30 USD and solar panel controller board, what for charging the accu are plentiness in stock everywhere.
