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.

Do capacitors in series have the same charge?

No, capacitors in series do not have the same charge. The charge on each capacitor depends on its capacitance and the voltage across it.


What is the total charge on capacitors in parallel connected to a circuit?

The total charge on capacitors in parallel connected to a circuit is the sum of the individual charges on each capacitor.


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.

How does charge sharing occur between two capacitors connected in a circuit?

Charge sharing between two capacitors connected in a circuit happens when one capacitor releases some of its stored charge to the other capacitor, equalizing their voltages. This occurs until both capacitors have the same voltage across them.
