the plates of capacitor are connected to the same battery so same potential difference will develop across the plates of capacitors, as a result charges of same magnitude will be stored, as the charges are being supplied by the same battery.
When connected to a d.c. supply, electrons are transferred from one plate and deposited on the opposite plate. This creates a potential difference across the two plates. This action continues until the capacitor's potential difference is equal (but opposite) to the potential difference of the d.c. source. If the source is then removed, the electrons cannot return to the original plate, other than through the dielectric, so the capacitor will hold that potential difference. By definition, the charge 'stored' on the capacitor is the amount of negative charge on the negative plate (not the sum of the charges on the two plates). Leakage current through the dielectric gradually reduces the potential difference across the plates.
A capacitor stores electrical charge. When the device is shut off, the charge will - over time - slowly bleed off. But immediately after shutdown, the charge is still present in the capacitor. In large capacitors, such as those found in air conditioning units, older style televisions, and microwave ovens, the stored charge can be strong enough to be potentially lethal. Service technicians have safe procedures for bleeding off the capacitor charge, but those not knowledgeable about electrical systems should not touch a chassis of above-mentioned items, even if shut off and unplugged. Stickers that say "Danger - High Voltage" mean exactly what they say.Another AnswerA capacitor does NOT store charge; it stores energy.The net charge on the plates of a capacitor is no different whether it is 'fully charged' or 'fully discharged'. It does not take charge from the supply and store it on its plates! It simply allows electrons from one plate to be transferred to the other, so there is no change in the overall amount of charge.What it does do is to store energy, expressed in joules.
capacitor is a device to store charge .it is based on the concept that when the potential of the capacitor is decreased it can gain some more charge so Q = CV where V is potential and Q is the charge stored then C is the capacitance. capacitance is the ability of the capacitor to store charge. expression for capacitance is C=ɛA/d where ɛis permittivity and A is area of capacitor plates ,d is plate separation.
A capacitor consists of two plates separated from one another by an insulator. These plates are normally thin foil and can be sandwiched around a very thin insulator and wrapped into a small package. Since there is an insulator between the plates, DC connected to the two plates cannot flow as long as you do not exceed the breakdown voltage of the insulator. AC current is a different story. Because the insulator is very thin and the effective plate area is relatively large, a negative charge building up on one plate causes electrons to be repelled from the opposite plate, and as the charge on the first plate reverses and becomes positive, the electrons in the opposite plate are attracted back again. This results in a matching alternating current flow on the opposite side of the capacitor.
The units of capacitance are called farads. A one farad capacitor is a capacitor with 1 volt potential difference with 1 coulomb of charge on the capacitor, C = Q/V or Q=CV So the charge held on your capacitor is Q = CV = 9Volts * 0.40*10-6Farads=3.6*10-6 Coulombs
No, in a charged capacitor, one plate has a positive charge and the other plate has a negative charge. The magnitude of the charges on the plates is equal and opposite, resulting in a net charge of zero for the entire capacitor.
No there will be additional charge for getting your license plate changed
In the State of Arizona, the license plate belongs to the debtor. They cannot charge you for your plate but they can charge you for inventory and storage of your personal property (which, incidently, includes your plate).
The electrical charge on the plate that causes the beam to bend toward it is negative. This negative charge creates an electric field that interacts with the positively charged ions in the beam, causing them to be attracted towards the negatively charged plate.
The plates a parallel-plate capacitor are 2.50 mm apart and each carries a charge of magnitude 80.0 nC. The plates are in a vacuum. The electric field between the plates has magnitude of 4.00x106 V/m.
Tectonic plate size does affect earthquake magnitude. Earthquakes happen when one plate slides above/below another plate, to do this it takes massive amounts of convection energy from the mantle to move the plate above. The larger the mass of the plate, the more energy is needed to move it which means that large plates have a lot of stored up energy in them before the quake in question. When the energy is released the plate boundary snaps releasing all the built up energy. As there was so much energy stored in the plate the more is released, causing a larger, more devastating earthquake.
A foam plate typically does not have a significant overall charge. However, it can acquire a temporary charge due to friction or contact with other charged objects, resulting in either a positive or negative charge depending on the circumstances.
The Indo-Australia plate subducted (slipped) underneath the Sunda Plate (A small plate trapped between the Eurasian and the Indo-Australian plates), displacing 1,600Km of plate boundary 15m vertically. This causes an underwater earthquake with magnitude 9.1 on the MMS (Moment Magnitude Scale). This caused 3 waves to be formed. Some of which travelled at 500mph.
Yes. All known earthquakes of magnitude 9.0 or greater have occurred at subduction boundaries.
a metalic sheet can be charge by induction and conduction to keep it on insulated stand
To find the electric field near the charged plate, you can use the formula for electric field due to a charged disk: ( E = \frac{\sigma}{2\epsilon_0}(1 - \frac{z}{\sqrt{z^2 + r^2}}) ), where ( \sigma ) is the charge density, ( \epsilon_0 ) is the permittivity of free space, ( z ) is the distance from the center of the disk and ( r ) is the radius. Substituting the values given, you can find the electric field magnitude near the plate.
A charged metallic plate is a thin rectangular (or square) sheet that carries a surface charge. Because metal is a conductor, you can assume that the surface charge is spread uniformly over the area of the plate.
