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.

How are the capacitors treated in the dc equivalent circuit of an amplifier?
In dc equivalent circuit of an amplifier all capacitors are replaced by open circuit because capacitor block dc. As , Xc=1/2πfC We know that that frequency of dc is zero so Xc will infinite so we replace all capacitors with open circuit.
What type of circuit is it when capacitors are combined with resistors?
RC Circuit
Why are charge capacitors dangerous?
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 .
What is super-thin slice of semiconducting material packed with microscopic circuit elements such as wires transistors capacitors logic gates and resistors?
integrated circuit
A closed circuit is a circuit in which charge?
Can flow
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.

Parallel capacitors total charge is?
The total charge stored by the circuit is also the sum of the individual values and is given as: QT = Q1 + Q2 + Q3 + etc
What is the formula for potential energy in an electrical system?
In an electric circuit, potential energy is usually understood as "stored charge." This is what capacitors do.
What type of circuit is it when capacitors are combined with resistors?
RC Circuit
What is capacitors in combination?
it is the tank circuit
What is difference between impedance and reactance?
Impedance is the net reactance(for Capacitors and inductors in the circuit) / Resistance of the circcuit whereas reactance is the prperty of the individual passive components ( only capacitors n inductors) to resist the flow of charge.
What will happen if dc is applied to the series and parallel combination of capacitors?
a capacitor must be supplied with only a.c supply because if it is supplied with d.c.supply the distance between the capacitors increases and it acts as a open circuit.
Why capacitors may pose an electric shock even in unpowered circuits?
Capacitors are used to store electricity in a circuit, so even when the circuit is unpowered, so long as it's still functional, it would still give off a small electric shock due to electric charge present in capacitor.
Why are capacitors essential in clamping circuit?

Why are discharge resistors connected across large industrial capacitors?
A: Discharge or bleeder resistance are there for only one reason to bleed the charge when the power if off and unless there is a paths for those capacitors to be discharged the power stored there can be lethal to humans or detrimental to the circuit
What are circuit patterns?
Circuit patterns are the collections of transistors, capacitors, and associated components and their interconnections.
