What else can I help you with?
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.
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
Why does a capacitor keep its charge after the supply is disconnected?
Yes, it can. Then you can use the charge to power something else. :)
How does a capacitor bank work?
They store charge between their plates in an electric field
For a parallel plate capacitor is The poynting vector points everywhere radially outward of the volume between plates?
No, the Poynting vector does not point radially outward in the volume between the plates of a parallel plate capacitor. The Poynting vector represents the direction and flow of electromagnetic energy, and in the case of a static electric field between the plates, the Poynting vector is zero within the volume between the plates.
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.
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.
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.
What is the relationship between the electric potential in a capacitor and the amount of charge stored on its plates?
The electric potential in a capacitor is directly proportional to the amount of charge stored on its plates. This means that as the amount of charge stored on the plates increases, the electric potential also increases.
How does the insertion of a dielectric affect the capacitance of a capacitor?
When a dielectric is inserted between the plates of a capacitor, it increases the capacitance of the capacitor. This is because the dielectric material reduces the electric field between the plates, allowing more charge to be stored on the plates for a given voltage.
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.
An air-filled parallel-plate capacitor is connected to a battery and allowed to charge up Now a slab of dielectric material is placed between the plates of the capacitor while the capacitor is still?
the charge on the capacitor had increased.
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.
What is the electric potential inside a parallel-plate capacitor and how does it relate to the charge and separation distance of the plates?
The electric potential inside a parallel-plate capacitor is directly proportional to the charge on the plates and inversely proportional to the separation distance between the plates. This means that as the charge on the plates increases, the electric potential also increases, and as the separation distance between the plates decreases, the electric potential increases.
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 are the three factors that determine the charge of a capacitor?
If you mean the capacity of the capacitor then, Factors are:- Area of of overlap of the plates Separation of the plates How good is the insulating material between the plates (the dielectric) If you mean how large a charge can be stored then, Factors are:- The capacitance of the capacitor (C). The applied voltage (V). Charge Q =CxV V cannot exceed the dielectric's breakdown voltage.
