Ampacity is the rated electrical current-carrying capacity for a conductor in a given situation, as addressed by the National Electric Code. It takes into account the AWG of the wire along with the type of insulation, proximity of other current carrying wires, ambient temperature, and other factors. ...more on Wikipedia about "Ampacity"
The ampere balance (also current balance or Kelvin balance) is an electromechanical apparatus used for the precise measurement of the SI unit of electric current, the ampere. It was invented by William Thomson, 1st Baron Kelvin. ...more on Wikipedia about "Ampere balance"
An anode (from the Greek άνοδος = 'going up') is the electrode in a device that electrons flow out of to return to the circuit. Literally, the path through which the electrons ascend out of an electrolyte solution. The other charged electrode in the same cell or device is the cathode. For electrons to flow through the anode a positive charge is applied to the anode (attracting electrons). ...more on Wikipedia about "Anode"
Band bending refers to the local change in energy of electrons at a semiconductor junction due to space charge effects. Because the common way to visualize the electron energy states and Fermi level in a material is to draw bands on an Energy vs. distance plot, band bending refers to bending in these diagrams and not in any physical form. ...more on Wikipedia about "Band bending"
A bifilar coil is an electromagnetic coil that contains two closely spaced, parallel windings. In engineering, the word bifilar describes wire which is made of two filaments or strands. It is commonly used to denote special types of winding wire for transformers. Wire can be purchased in bifilar form, usually as different colored enamelled wire bonded together. For three strands, the term trifilar coil is used. ...more on Wikipedia about "Bifilar coil"
The Bridgman effect, also called the internal Peltier effect, is a phenomenon that occurs when an electric current passes through an anisotropic crystal - there is an absorption or liberation of heat because of the non-uniformity in current distribution. ...more on Wikipedia about "Bridgman effect" If you like you could tell us your opinion about shortopedia
Capacitance is a measure of the amount of electric charge stored (or separated) for a given electric potential. The capacitance is usually defined as the total electric charge placed on the object divided by the potential of the object: ...more on Wikipedia about "Capacitance"
A cathode is the electrode at which electrons go into a cell, tube or diode whether driven externally or internally. It comes from the Greek word κάθοδος meaning, 'going down'. The other charged electrode in the same cell or device is the anode. ...more on Wikipedia about "Cathode"
A cattle prod, also called a stock prod, is a handheld device commonly used for stimulating movement in cattle or other livestock through the use of a (relatively) low voltage electric shock. ...more on Wikipedia about "Cattle prod"
In radio communications, characteristic impedance ( acoustic impedance or sound impedance) of a uniform transmission line is the impedance of a circuit that, when connected to the output terminals of a line of arbitrary length, causes the line to appear infinitely long. This is sometimes called surge impedance. ...more on Wikipedia about "Characteristic impedance"

The current divider rule (or CDR) is used to find the electrical current flowing through an impedance or other circuit when it is connected in parallel with another impedance. It is similar in form to the voltage divider rule. The key difference, however, is that the numerator of the equation is the impedance you are not considering. ...more on Wikipedia about "Current divider rule"
The daraf is the unit of electrical elastance (symbol: F-1), the ability of an electric potential to charge a capacitor; it is the reciprocal of the farad. Proposed by Arthur Edwin Kennelly in 1936 as a backwards spelling of farad, the daraf is not a recognized SI unit. ...more on Wikipedia about "Daraf" Simply shortopedia! shortopedia
In plasma physics, the Debye length, named after the Dutch physical chemist Peter Debye, is the scale over which mobile charge carriers (e.g. electrons) screen out electric fields in plasmas and other conductors. In other words, the Debye length is the distance over which significant charge separation can occur. In space plasmas where the electron density is relatively low, the Debye length may reach macroscopic values, such as in the Magnetosphere, Solar wind, Interstellar medium and Intergalactic medium (see table): ...more on Wikipedia about "Debye length"
A dielectric, or electrical insulator, is a substance that is highly resistant to flow of electric current. ...more on Wikipedia about "Dielectric"
Dielectric Breakdown Model (DBM) is a macroscopic mathematical model combining the Diffusion Limited Aggregation model with electric field. It was developed by Niemeyer, Pietronero, and Weismann in 1984. It describes the patterns of dielectric breakdown of solids, liquids, and even gases, explaining the formation of the branching, self-similar Lichtenberg figures. ...more on Wikipedia about "Dielectric Breakdown Model"

Direct current (DC or "continuous current") is the constant flow of electric charge from high to low potential. This is typically in a conductor such as a wire, but can also be through semiconductors, insulators, or even through a vacuum as in electron or ion beams. In direct current, the electric charges flow in the same direction, distinguishing it from alternating current (AC). A term formerly used for direct current was Galvanic current. ...more on Wikipedia about "Direct current"
Displacement current is a quantity related to a changing electric field; it is not a real current (movement of charge) in a vacuum, but it has the units of current, as movement of charge does, and has an associated magnetic field. It was postulated in 1865 by James Clerk Maxwell when formulating what are today known as Maxwell's equations. ...more on Wikipedia about "Displacement current"
An electric arc is an electrical breakdown of a gas which produces an ongoing plasma discharge, similar to the instant spark, resulting from a current flowing through normally nonconductive media such as air. A slightly archaic term is voltaic arc as used in the phrase "voltaic arc lamp". ...more on Wikipedia about "Electric arc"
Electric charge is a fundamental conserved property of some subatomic particles, which determines their electromagnetic interactions. Electrically charged matter is influenced by, and produces, electromagnetic fields. The interaction between charge and field is the source of one of the four fundamental forces, the electromagnetic force. ...more on Wikipedia about "Electric charge"
The term electrical breakdown has several similar but distinctly different meanings. The term may apply to a failure of an electric circuit or system with consequent lack of function. ...more on Wikipedia about "Electrical breakdown"
Electrical conductance is the reciprocal of electrical resistance. It is a measure of how easily electricity flows along a certain path through an object. The SI derived unit of conductance is the siemens (symbol S, equal to 1/ Ω; alias the "mho"). In September of 1885, Oliver Heaviside coined this term. ...more on Wikipedia about "Electrical conductance" www.shortopedia.com never sleeps.
