as far i think,there is no current flowing between two fully charged capacitor.current flow in a capacitor happens until it gets fully charged.if it is fully charged then there is no lack of potential,so no current flow.

Why apply in dc voltage in winding meggering time?
The DC between windings is analogous to DC on capacitor plates. Windings, like capacitors, require time to charge up to the applied voltage, at which, there will be a constant current. Since Voltage / current= Resistance, the Megohm reading will change/increase until the windings are fully charged to a quiescent, steady leakage current. When current is at a stable leakage level, you will have an accurate reading. xfrmrman
What would happen to the current flow in a dc circuit when the capacitor is fully charged?
A capacitor charge as a time constant of R resistance C capacitance in ufd and it is defined as 63% for one time constant for the constant voltage source. Electronic engineers assume that a capacitor is fully charged by a 5 times constant. however mathematically speaking it will never be fully charged for obvious reasons. Therefore the answer is current will never stop/
What are the advantages and disadvantege of capacitors?
Capacitors are very good for storing small quantities of electrical energy, for creating timing circuits based on the time it takes a capacitor to charge, and there are also excellent uses of their characteristic of conducting a varying voltage.
How long should you charge a spy pen?
Until its fully charged, you idiot.
What are indications that lead acid battery is fully charged?
There are two measures, cell voltage and specific gravity of the electrolyte. Cell voltage is the simplest to measure. For most automotive, flooded cell (having liquid electrolyte) batteries, 12.6 volts is considered full charge, although it is typical to have 13 volts or a bit over. The specific gravity of a fully charged battery, measured with a hydrometer, is 1.265.
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.

Why does a fully charged capacitor show infinite resistance?
The voltage-current relationship for a capacitor is i = C dv/dt, where i is the current flowing through, C is the capacitance and dv/dt is the time rate change of the voltage across that capacitor. So, when a capacitor is fully charged, the voltage no longer changes with time (the derivative, dv/dt, is now 0). As can be seen from the equation, the current would therefore be 0. Anything with 0 current flowing through is an open circuit, and can be treated like a resistor with infinite resistance (in models, anyway). Practically speaking, capacitors aren't this perfect, but you will still have an extremely high resistance once fully charged (voltage changes negligibly after charging).
A lamp is connected to a battery if a capacitor is inserted in the positive wire between the battery and the lamp what will happen?
large capacitors will become charged in a fraction of a second if a DC voltage is applied to its terminalsonce a capacitor becomes fully charge it acts as an open circuit to direct current in other words, once the capacitor charged by a DC voltage, the current will cease to flow in the branch of the circuit which contains the capacitor.a capacitor also offers opposition known as (capacitive reactance) to alternating current. it does not , however ,act as an open circuit to when an a-c alternating current voltage is applied.
What are the uses of capacitors in your day to day life?
Capacitors are used extensively in electronic devices. These include computers, televisions, DVD players...More uses of Capacitors· ICD (implantable Cardiac Defibrillator)o Acts as a pacemaker, but if the heart stops it gives out an electric shock, to do this is uses components called Capacitors· Solar panels· Lego Motors and Solar Panelso Using a LEGO solar panel or a LEGO motor as generator, the capacitor can be charged and discharged just like a rechargeable battery. The capacitor can be used for powering a LEGO motor. When the capacitor is fully charged, operating voltage is normally 2.5V. A red diode lights flashes when fully charged. The capacitor is protected against reverse polarity.· Computers· T.V· DVD players· Medical Lasers· Defibrillators· Camera flashes

Is there any electric current in the battery not yet placed in the car?
Yes, all batteries are fully charged when the leave the factory.
Why does the current in a capacitor become zero or almost zero when fully charged?
because in a capacitor only charges are stored so the stored charges are gives the zero current
Does your havoc heli have to be fully charged so it works right?
No, but it will work better if it is fully charged.
How do you know when the spynet video watch is fully charged?
When it is charging the screen reads: Battery Charging. When it is fully charged it reads: Battery Charged.
What are typical voltage for fully charged and half charged batteries?
A fully charged 12 volt automotive battery should have 12.68 volts.
What is a charged body?
A charged body is a body that was fully charged that can either positively or negatively charged.
