17.1: The Capacitor and Ampère''s Law
A word about signs: The higher potential is always on the plate of the capacitor that has the positive charge. Note that Equation ref{17.1} is valid only for a parallel plate capacitor. Capacitors come in many different geometries and the formula for the capacitance of a capacitor with a different geometry will differ from this equation.
18.4: Capacitors and Dielectrics
Capacitors in Series and in Parallel: The initial problem can be simplified by finding the capacitance of the series, then using it as part of the parallel calculation. The circuit shown in (a) contains C 1 and C 2 in series. However, these are both in parallel with C 3.
5.12: Force Between the Plates of a Plane Parallel Plate Capacitor
No headers We imagine a capacitor with a charge (+Q) on one plate and (-Q) on the other, and initially the plates are almost, but not quite, touching. There is a force (F) between the plates. Now we gradually pull the plates apart (but the separation remains ...
5.12: Force Between the Plates of a Plane Parallel Plate Capacitor
We imagine a capacitor with a charge (+Q) on one plate and (-Q) on the other, and initially the plates are almost, but not quite, touching. There is a force (F) between the plates. Now we gradually pull the plates apart (but the separation remains small enough that it is still small compared with the linear dimensions of the plates and we ...
Solved A 3300-pF air-gap capacitor is connected to a 28-V
A 3300-pF air-gap capacitor is connected to a 28-V battery. Part A. If a piece of mica (K= 7) is placed between the plates, how much charge will flow from the battery? Express your answer using one significant figure and include the appropriate units.
Capacitor
A capacitor is a passive component which stores energy as charge in the electrical field between two conducting plates called electrodes. Capacitors can release the stored …
electrostatics
In a capacitor, the plates are only charged at the interface facing the other plate. That is because the "right" way to see this problem is as a polarized piece of metal where the two polarized parts are put facing one another. In principle, each charge density generates a field which is $sigma/2 epsilon$. It is just that the actual geometry ...
Spark-gap transmitter
The transmitter works in a rapid repeating cycle in which the capacitor is charged to a high voltage by the transformer and discharged through the coil by a spark across the spark gap. [11] [16] The impulsive spark excites the resonant circuit to "ring" like a bell, producing a brief oscillating current which is radiated as electromagnetic waves by the antenna. [11]
8.2: Capacitors and Capacitance
A capacitor is a device used to store electrical charge and electrical energy. It consists of at least two electrical conductors separated by a distance. (Note that such electrical conductors are sometimes referred to as "electrodes," but more correctly, they are "capacitor plates.") The space between capacitors may simply be a vacuum ...
Spherical Capacitor
Spherical Capacitor The capacitance for spherical or cylindrical conductors can be obtained by evaluating the voltage difference between the conductors for a given charge on each. By applying Gauss'' law to an charged conducting …

Fixing endshake/cylinder gap on a Colt-style cap and ball revolver ...
What is the proper way to fix cylinder gap and cylinder endshake on a colt-style cap and ball revolver? I have one where the gap measures up to 0.020", is this still safe to shoot? My understand is that for cap and ball revolvers, the whole cylinder revoils back when shot.

PCB Layout Recommendations for BGA packages
These trends have made BGA (ball grid array) the package of choice in the design of modern electronic products. BGA packages are used to connect an IC to a printed circuit board (PCB), and a grid of tiny solder balls arranged in a pattern on the bottom of the package. The solder balls act as the connection points between the IC and the …
