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".
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 ...
An inductor is characterized by its inductance, which is the ratio of the voltage to the rate of change of current. In the International System of Units (SI), the unit of inductance is the henry (H) named for 19th century American scientist Joseph Henry. In the measurement of magnetic circuits, it is equivalent to weber / ampere .

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 rigorous full-wave version of the PEEC method is called (Lp,P,R,t) PEEC, where Lp is partial inductance, P is the Maxwell potential coefficient (inverse of capacitance), R is resistance, and t is the time-delay. If available, a reduced model of the full-wave version can be used.
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 constant of proportionality is termed the inductance. The unit of inductance is the henry, named after Joseph Henry, a contemporary of Faraday. One henry is the inductance that will induce a potential difference of one volt if the current through it changes at a rate of one ampere per second.
