Metallized plastic polypropylene (German: Metallisierter Kunststoff Polypropylen), a type of plastic-film capacitor; Monobasic potassium phosphate, another name for monopotassium phosphate (KH 2 PO 4). The K comes from Latin kalium, which means potassium. Not to be confused with magnesium potassium phosphate (MgKPO 4), a type of quick setting ...
Meaning SI unit of measure alpha: alpha particle: angular acceleration: radian per second squared (rad/s 2) fine-structure constant: unitless beta: velocity in terms of the speed of light c: unitless beta particle: gamma: Lorentz factor: unitless photon: gamma ray: shear strain: radian
Capacitors are different from resistors and inductors in that the impedance is inversely proportional to the defining characteristic; i.e., capacitance. A capacitor connected to an alternating voltage source has a displacement current to flowing through it.
Capacitors for AC applications are primarily film capacitors, metallized paper capacitors, ceramic capacitors and bipolar electrolytic capacitors. The rated AC load for an AC capacitor is the maximum sinusoidal effective AC current (rms) which may be applied continuously to a capacitor within the specified temperature range.
It is common for electrical components to have slightly reduced capacitances at extreme frequencies, due to slight inductance of the internal conductors used to make capacitors (not just the leads), and permittivity changes in insulating materials with frequency: C is very nearly, but not quite a constant.
A branch of physics that studies atoms as isolated systems of electrons and an atomic nucleus. Compare nuclear physics. atomic structure atomic weight (A) The sum total of protons (or electrons) and neutrons within an atom. audio frequency A periodic vibration whose frequency is in the band audible to the average human, the human hearing range.
In electricity (electromagnetism), the electric susceptibility (; Latin: susceptibilis "receptive") is a dimensionless proportionality constant that indicates the degree of polarization of a dielectric material in response to an applied electric field.
The capacitance of a capacitor is one farad when one coulomb of charge changes the potential between the plates by one volt. [1] [2] Equally, one farad can be described as the capacitance which stores a one-coulomb charge across a potential difference of one volt. [3] The relationship between capacitance, charge, and potential difference is linear.
