Charge Capacitors , like all capacitors shift the voltage 90 degrees, tiny one form tuned circuits and do a multiple of functions like blocking DC and allowing AC to pass . But as your name indicates a charge or charged Capacitor can kill you with shock . Or simply knock you silly for a fraction of second .

Can capacitors charge on an open circuit?
No. Capacitors need current to charge or discharge. In an open circuit, current is impossible, so they will stay at the last known charge, depending on the amount of leakage current.
Are pyranol capacitors dangerous?
Yes, Pyranol is a nasty substance.
What are series capacitors?
Capacitors are said to be connected together "in series" when they are effectively "daisy chained" together in a single line. The charging current ( iC ) flowing through the capacitors is THE SAME for all capacitors as it only has one path to follow. Then, Capacitors in Series all have the same current flowing through them as iT = i1 = i2 = i3 etc. Therefore each capacitor will store the same amount of electrical charge, Q on its plates regardless of its capacitance. This is because the charge stored by a plate of any one capacitor must have come from the plate of its adjacent capacitor. Therefore, capacitors connected together in series must have the same charge. QT = Q1 = Q2 = Q3 , etc.
Can a capacitor be gradually charged by lesser capacitors?
A: SURE capacitors in parallel will share the charge. But don't expect a .0001 mfd capacitor to charge a 1000 mfd capacitor. It just does not have the power stored to effectively charge the 1000 mfd. EXAMPLE 1litter of water cannot fill up a 5 litter container
Which component requires a constant electrical charge and a periodic refresh of the circuits?
While your question is unclear and shows that you are somewhat confused, I believe you are probably asking about Dynamic Random Access Memory (DRAM) devices. These devices store data as electrical charge in billions or trillions of microscopic capacitors. Because no insulator is perfect the charge in these capacitors slowly leaks off, meaning to avoid losing the date the memory must be refreshed by periodically reading every capacitor and writing it back.I have no idea what you were thinking when you wrote "requires a constant electrical charge" as the charge on the capacitors when they need to be refreshed may be half or less of the charge on the capacitors when they were first written or after they have been refreshed. The charge on the capacitors is never constant, which is the reason they need refreshing in the first place.The first Dynamic Memory was built in 1941 by John Vincent Atanasoff and Clifford Berry, it used capacitors but was not randomly accessible. It had a storage capacity of sixty 50 bit signed binary words and was refreshed once per second.Later Dynamic Memories included delay line memories (both mechanical and electrical) and CRT DRAM that stored the charge as tiny spots on the inside face of the vacuum tube.
How many capacitors are use in a circuit?
Capacitors store charge. There are many applications for their use. There is no set amount of capacitors in a circuit since it is application dependent.
Can capacitors charge on an open circuit?
No. Capacitors need current to charge or discharge. In an open circuit, current is impossible, so they will stay at the last known charge, depending on the amount of leakage current.
Are pyranol capacitors dangerous?
Yes, Pyranol is a nasty substance.
How to calculate capacitors of 120uf and charge 2.4V?
Your question doesn't makes sense, as charge isn't measured in volts.
What devices have the ability to store current?
Batteries and capacitors store electric charge.
What is the ratio of capacitance of capacitors?
ratio of capacitance of capacitor is given by charge\potential
Whats is the use of capacitors?
capacitor is charge holding device ,it holds charge on two plates named as +ve and -ve
Do capacitors really only work in ac alternating current?
Not only for AC. Some applications use capacitors to hold a steady charge for periods of time.
What is the function of a capacitors shortly?
*to store charge. *to smooth out(reduce ripple on dc) a voltage
How do you use a diode to charge your saltwater capacitors with ac voltage?
Simply include the diode in one of the AC supply lines to your capacitor. (not sure what a salt water capacitor is) but, all capacitors only store charge, which is discharged as a DC current.

How does the toast know when to pop the toast?
The toaster contains a variable resistor (timer knob on the outside) that changes the charge rate of the capacitors. When the capacitors are fully charged, the release the toast.
