Henry (unit) The henry (symbol: H) is the SI derived unit of electrical inductance. If a current of 1 ampere flowing through the coil produces flux linkage of 1 weber turn, the coil has a self inductance of 1 henry. The unit is named after Joseph Henry (1797–1878), the American scientist who discovered electromagnetic induction
Named after: Joseph Henry
Define inductor and inductance of inductor with its unit? An inductor is a device that resists a change in current. The windings in the inductor form a magnetic field that serve the maintain the electric current by bucking an increas … e in current or by sustaining a decrease in current.
Definition of Inductance. If a changing flux is linked with a coil of a conductor there would be an emf induced in it. The property of the coil of inducing emf due to the changing flux linked with it is known as inductance of the coil. Due to this property all electrical coil can be referred as inductor.
What is an Inductor. The simplest inductor consists of a piece of wire. A piece of #22 wire which is approximately 100 mm ( 4″ ) long has a measured inductance of 0.14 uH. Well mine did because I measured it on an inductance meter (see kits) operating at about 740 Khz. – …
The Inductor. In its most basic form, an Inductor is nothing more than a coil of wire wound around a central core. For most coils the current, ( i ) flowing through the coil produces a magnetic flux, ( Nφ ) around it that is proportional to this flow of electrical current. The Inductor, also called a choke,
Jul 02, 2017 · Resistance is to a resistor as inductance is to a(n) ___________. That was easy. The answer is inductor. Let’s try another: Resistor is to heat as inductor is to ___________. That one was a bit harder. Let’s take a look at the units: The answer appears to be related to energy storage.

The standard unit of inductance is the henry, abbreviatedH. This is a large unit. More common units are the microhenry, abbreviated µH (1 µH =10-6H) and the millihenry, abbreviated mH (1 mH =10-3 H). Occasionally, the nanohenry (nH) is used (1 nH = 10-9 H).
The inductance of a circuit depends on the geometry of the current path as well as the magnetic permeability of nearby materials. An inductor is a component consisting of a wire or other conductor shaped to increase the magnetic flux through the circuit, usually in the shape of a coil or helix.

Inductors & Inductance Calculations. Inductors are passive devices used in electronic circuits to store energy in the form of a magnetic field. They are the compliment of capacitors, which store energy in the form of an electric field. An ideal inductor is the equivalent of a …
May 02, 2009 · The unit measure a resistor is ohm,that of capacitor is farad and that of inductor is henry.
The inductor is a wire shaped so that the magnetic field will be much stronger. The reason an inductor works the way it does is because of this magnetic field. This field does some magic physics stuff that resists alternating currents.
