plate capacitor उदाहरण वाक्य

Assuming a parallel plate capacitor with uniform electric field, and neglecting fringing effects around the edges of the plates, differentiation provides:
With the filament removed, the PMC is analogous to parallel plate capacitor with a high resistance of several ? between the contacts.
Often it is chosen to only have 10-fold capacitance compared to the MCP-anode capacitance and is implemented as a plate capacitor.
A common form is a parallel-plate capacitor, which consists of two conductive plates insulated from each other, usually sandwiching a dielectric material.
A physical example is : Take a parallel-plate capacitor, which has a " leaky " dielectric with permittivity 1 but a finite resistivity.

This value can be used to calculate capacitance values using the standard formula for conventional plate capacitors if only the surface of the electrodes is known.
In a parallel plate capacitor, capacitance is very nearly proportional to the surface area of the conductor plates and inversely proportional to the separation distance between the plates.
The layers in the board contributing to the capacitive properties also function as power and ground planes, and have a dielectric in between them, enabling them to operate as a parallel plate capacitor.
Nearly all conventional industrial capacitors except some special styles such as " feed-through capacitors ", are constructed as " plate capacitors " even if their electrodes and the dielectric between are wound or rolled.
For a surface charge distribution ( a good approximation for charge on a plate in a parallel plate capacitor ) where gives the charge per unit area at position, and is an infinitesimal element of area,
