An electronic component designed to add inductance to a circuit is called an inductor. It typically consists of a coil or helix of wire. The term inductance was coined by Oliver Heaviside in May 1884, as a convenient way to refer to "coefficient of self-induction".
In general, the relation between the emf in a wire loop encircling a surface Σ, and the electric field E in the wire is given by = where dℓ is an element of contour of the surface Σ, combining this with the definition of flux =, we can write the integral form of the Maxwell–Faraday equation =
The henry (symbol: H) is the unit of electrical inductance in the International System of Units (SI). [1] If a current of 1 ampere flowing through a coil produces flux linkage of 1 weber turn, that coil has a self-inductance of 1 henry. The unit is named after Joseph Henry (1797–1878), the American scientist who discovered electromagnetic induction independently of and at about the same ...
Initially, a region of California known for a large number of electronics technology firms. sine wave The waveform of the mathematical sine function; a fundamental wave shape, free of harmonics. single-phase electric power An alternating current power system using only two wires, where peak voltages in each wire occur at the same time.
The definition of surface integral relies on splitting the surface Σ into small surface elements. Each element is associated with a vector dA of magnitude equal to the area of the element and with direction normal to the element and pointing "outward" (with respect to the orientation of the surface).
k is the coupling coefficient, Le1 and Le2 is the leakage inductance, M1 (M2) is the mutual inductance. An inductively coupled transponder consists of a solid state transceiver chip connected to a large coil that functions as an antenna. When brought within the oscillating magnetic field of a reader unit, the transceiver is powered up by energy ...
This glossary of power electronics is a list of definitions of terms and concepts related to power electronics in general and power electronic capacitors in particular. For more definitions in electric engineering, see Glossary of electrical and electronics engineering .
A more refined model also includes a series inductance to represent the effects of its lead inductance (resistors constructed as a spiral have more significant inductance). A capacitance in parallel may be added to represent the capacitive effect of the proximity of the resistor leads to each other. A wire can be represented as a low-value ...
