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
What is the difference between capacitor and capacitance?
A capacitor is a device that stores an electrical charge, or if you prefer- resists any change in voltage applied to it. Capacitance is a measure of the size or ability of a capacitor to do that. This is the Farad
What does a capacitor store if the sum of charges of both capacitors is zero?
it may consist much of negative and positive chargeAnswerA capacitor stores energy within an electric field set up between its plates. It does not 'store' charage, as the net charge is the same both before and after the capacitor has been 'charged' (unfortunate use of the word!). What it does is to enable charge to be separated, with one plate then becoming negative with respect to the other, resulting in an electric field between the two plates.When we describe the 'amount of charge' on a capacitor, by convention, we mean the amount of negative charge stored on its negative plate, and not the sum of this and the amount of positive charge on its positive plate!
What is the difference in a 5 uf and a 4 uf capacitor?
1 uf (i.e. 5uf - 4uf = 1uf) Note: uf=micro Farads. A Farad is a unit of charge capacitance. You can think of it as charged electrons stored in a small package.
What is flying capacitor?
An external or secondary circuit drives the switching, typically at tens of kilohertz up to several megahertz. The high frequency minimizes the amount of capacitance required as less charge needs to be stored and dumped in a shorter cycle. The capacitor used as the charge pump is typically known as the "flying capacitor".
What happens to the capacitance fi the charge on the plates of a capacitor is doubled?
The capacitance doesn't depend on the charge stored in it. The capacitor has the same capacitance whether it's charged by a DC and just holding it, or in an AC circuit where the charge on it keeps changing and reversing, or in a box on the shelf connected to nothing and not charged at all.
A 5 uf capacitor has 5x10 -4 coulombs a charge stored in its plates find the voltage across the capacitor?
A5uf capacitor has 5*10-4 coulombs of charge stored on its plates

What is stored charge?
In a capacitor it is a build up of electrons on a plate.
What is the total capacitance of this arrangement the charge of each capacitor and the voltage across the last capacitor and the energy stored in it?
(a) what is the total capacitance of this arrangement (B) the charge stored on each capacitor (C) the voltage across the 50 micro farad capacitor and the energy stored in it. 20v and 20+30+50 micro farad
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
If the capacitor store the charge from the magnetic field then the capacitor is called?
it wouldn't store a charge from the magnetic field, only the current induced on the circuit would be stored
How does a capacitor get charged?
a capacitor is used to store charge for longer period of time.in odder to understand that how a capacitor gets charged consider two parallel metal plates.these plates are neutral having equal amount of positive and negative charges.now connect these plates to the opposite terminals of a battery.the electrons present in the plate connected to the positive terminal of a battery will be attracted by the positive terminal leaving the plate positively charged.now these electrons are pushed by the battery to its negative terminal which repels these electrons to the plate connected to it making it negatively charged. now the battery is disconnected.so in this way the plates of a capacitor gets charged.as these plates have opposite charges stored on them force of attraction exist between them enabling a capacitor to store charge for longer periods of time.

1 For a parallel plate capacitor which is being charged out What the incorrect statement is?
Energy stored in the capacitor does not enter it through the connecting wire through the space around the wires and plates of capacitor.
What is capacitor function?
The capacitor is used to store the charge applied to it.This stored charge can be used to absorb voltage spikes and voltage drops.AnswerIt's a misconception that a capacitor stores charge. In fact, it stores energy. The net charge on a fully-charged capacitor is the same as on a fully discharged capacitor.
Which electronic component can store a charge?
A parallel plate capacitor is an electrical component which can store charge. The charge is stored according to the equation: qo = q(1-e-t/RC) [in a charginr circuit.]
