Understanding Capacitors

When the capacitor is fully charged (voltage between the plates is equal to the source voltage), the capacitor stops charging. When the battery is removed from the capacitor, the two plates will retain its charge for a certain time. Thus, it …

Capacitor Basics, Working and Different Types of Capacitors …

The maximum voltage this sort of arrangement can handle is the voltage of the smallest capacitor, since in the voltage is common to all the caps. An example should clear this up. Supposing you have two capacitors, one with the ratings 25V 470uF and the other 35V 1000uF. The total capacitance would be 470uf + 1000uF = 1470uF.

Solved The same voltage is applied between the plates of two

The same voltage is applied between the plates of two different capacitors. When used with capacitor A, this voltage causes the capacitor to store 1 7 mu C of charge and 5. 4 x 1 0-5 J of energy. When used with capacitor B, which has a capacitance of 7. 2 mu F, this voltage causes the capacitor to store a charge that has a ...

Solved The same voltage is applied between the plates of two

The same voltage is applied between the plates of two different capacitors. When used with capacitor A, this voltage causes the capacitor to store 18 μC of charge and 6.7 x 10-5 J of energy. When used with capacitor B, which has a capacitance of 5.2 μF, this voltage causes the capacitor to store a charge that has a magnitude of qB. Determine qB.

electrostatics

If two charged plates are connected together, the total charge on the two does not change. If the wires (and plates) have no resistance, then connecting two charged capacitors can result in LC oscillations (depending on voltages and polarities). If two charged capacitors are connected together (with resistance) they will come to the same …

Parallel Capacitors with different voltages

The scenario you describe is nonsensical and cannot be analyzed using normal circuit analysis techniques. Suppose you have two ideal capacitors with two different voltages across them. The voltage across a capacitor cannot change instantaneously because an infinite current would be required.

Why voltage is not the same for the capacitors in series?

Because two plates of the capacitor C1 are same in material and geometry. Similarly left plate of C2 has to acquire to the potential +P. If this happens then the voltage of C1 and C2 will be same V and net voltage of the two capacitors will become 2V which is wrong. If someone could clarify this confusion it would be a big help.

19.2: Electric Potential in a Uniform Electric Field

Example (PageIndex{1}): What Is the Highest Voltage Possible between Two Plates? Dry air will support a maximum electric field strength of about (3.0 times 10^{6} mathrm{V/m}). Above that value, the field creates enough ionization in the air to make the air a conductor. This allows a discharge or spark that reduces the field.
