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.
How are the terms capacitor and capacitance related?
Capacitor is the name of the device and capacitance is a measure of farads in the capacitor. Capacitance is the capacity for storing charge in the capacitor as measured in farads, micro farads or millifarads.
What happens to a capacitance if the plates have a charge that is doubled?
The capacitance won't change, or it won't change significantly. The capacitance is simply the charge/voltage ratio - and if the charge doubles, the voltage will also double. Capacitance is determined by the physical properties of the capacitor (plate separation, plate area, and dielectric). The unit for capacitance (farad) is a coulomb per volt. So the capacitance is the amount of charge (coulombs) that the plates will hold at a given voltage.
What has happened when a light bulb has burn out?
it simply means that a wire from the light bulb is joined or connected to the charged plates of the capacitor.resulting to discharged of the capacitor.
How does a condenser convert gas into liquid?
steam from the turbine passes through tubes that are suurounded by water that is cooler than the steam the steam is therefore cooled the steam then turns back into water condensation =condensor
When a capacitor is neutralized where does excess charge go back to?
A capacitor is "charged" when the charge on the two plates is not the same. When you neutralize or "discharge" the capacitor you are transferring charge back to the low plate, so that the charge on both plates is the same.
Why does a charged capacitor have a net charge of zero?
A charged capacitor consists of two conductive plates with opposite charges. These charges cancel each other out, resulting in a net charge of zero for the capacitor as a whole.
What current exists in a capacitor when it is fully charged in an RC circuit?
When a capacitor is fully charged in an RC circuit, it holds a stored electrical charge. This charge creates an electric field between the capacitor plates, with no current flowing through the circuit at that moment.
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.
Charge buildup between the plates of a capacitor stops when?
Charge buildup between the plates of a capacitor stops when the current flow through the capacitor goes to zero.
Suppose a parallel plate capacitor (with capacitance) is connected to a battery, what is the relationship between the charge stored on the capacitor and the potential difference across its plates?
The relationship between the charge stored on a capacitor and the potential difference across its plates is that the charge stored on the capacitor is directly proportional to the potential difference across its plates. This relationship is described by the formula Q CV, where Q is the charge stored on the capacitor, C is the capacitance of the capacitor, and V is the potential difference across the plates.
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
How a capacitor store charge?
by using capacitor plates. The length,area ,thickness and type of the plate determines the amount of charge a capacitor can store.
What is the use capacitor?
capacitor is charge holding device ,it holds charge on two plates named as +ve and -ve
If you take out the battery in a capacitor before inserting a dielectric will there still be charge on the dielectric?
The charge in a capacitor is between the plates. The dielectric is only an insulator that allows the plates to be very close without touching and discharging the charge. There is no battery in a capacitor.
Does charge on a parallel plate capacitor depend on distance between the plates?
No, the charge on a parallel plate capacitor does not depend on the distance between the plates. The charge stored in the capacitor is determined by the voltage applied across the plates and the capacitance of the capacitor. The distance between the plates affects the capacitance of the capacitor, but not the charge stored on it.
What is the effect of changing the distance between the plates of a capacitor on the charge stored on the plates?
Changing the distance between the plates of a capacitor affects the charge stored on the plates. As the distance decreases, the capacitance increases, leading to a higher charge stored on the plates. Conversely, increasing the distance between the plates decreases the capacitance and results in a lower charge stored on the plates.
