Definitions for **"Inductance"**

the measure of a magnetic field. Measured in Henries. See Inductor for details.

The power of an electric current to develop an electromotive force in its own or an adjacent circuit.

The voltage across an inductor is directly proportional to the rate of change of the current through it divided by the rate of change of time (difference current/difference time = di/dt). The proportionality constant which makes this true is L, the inductance of the inductor component. It is denoted by and its units are the Henry (H). Therefore, the voltage across an inductor is given by v = L*(di/dt).

A wire carrying an electrical current creates a magnetic field around it. When that magnetic field penetrates into another wire, it causes an electric current in the second wire with the same waveform as the current in the first wire. This magnetic transfer is called inductance. This is particularly bad in audio when AC power lines or amplifier speaker lines are run next to (parallel) other low-current carrying lines (microphone/line level). The same effect occurs if the lines are coiled and on top of each other. The best defense against this type of interference is to keep different current carrying cables away from each other; run them in different conduits. If they need to cross each other, do so at 90-degree angles.

The property of a circuit by which energy is stored in the form of an electromagnetic field.

A property of a conductor that allows is to store energy in a magnetic field which is induced by a current flowing through it. Inductance is measured in units of Henries (the base unit is a Henry).

The ability of a device to store energy in the form of a magnetic field.

an electrical device that introduces inductance into a circuit

The property by which an electromotive force (emf) is induced in a conductor when the magnetic field is changing about it. This is usually caused by changes in the current flow in the circuit or in a neighboring circuit.

The electrical equivalent to mechanical inertia; that is, the property of a circuit, which has a tendency to resist current flow when no current is flowing, and when current is flowing has a tendency to maintain that current flow. Powertec measures inductance (line-to-line) with a bridge at 1000 Hz and with the rotor positioned so the back-EMF waveform is at the peak of the sinusoid.

Mutual inductance is the property that exists between two current carrying conductors or coils when magnetic lines of force from one link with those of the other.

Usually measured in milliHenrys (mH), a measure of a coil's effect upon alternating current electricity.

The property of an electric circuit that opposes a change in current flow.

The process of storing electrical energy in magnetic fields. An inductor is any element in an electrical circuit having a magnetic field, though usually by design these elements are coils and transformers. When inductance and frequency are considered together, a value of inductive reactance, measured in Ohms, is formed. This reactance looks like resistance to current flow for a signal of a given frequency. Inductive reactance and capacitive reactance together form reactive impedance.

An induced voltage producing a resistance in an alternating current circuit.

the ability of a conductor to produce an induced voltage when there is a variation in the electrical current passing through it.

The property of a circuit whereby a change in current causes a change in voltage. The unit of inductance is the Henry: the amount of inductance required to generate one volt of induced voltage when the current is changing at the rate of one ampere per second. See Inductor, Coil.

Two times energy stored in the magnetic field, divided by the square of the applied current. High inductance means that a desired magnetic field can be achieved with a low current, though at the expense of slow response.

The property of a circuit or component that tends to oppose changes in current due to the magnetic field that is a result of the current itself. The unit of inductance is the henry, abbreviated "H". The schematic representation of inductance is designated as "L."

A circuit's opposition to a change in current flow.

The effect where energy is stored in a magnetic field. An inductor is an electronic component made specifically to store energy by using a magnetic field. Inductors are also used to differentiate between frequencies in applications such as crossover networks. An inductor has low impedance at low frequencies (short circuit at DC) and its impedance increases as frequency increases.

The property of a conductor whereby a voltage is induced into it as a result of a changing current.

The property of an electric circuit by which a varying current in it produces a varying magnetic field that introduces voltages in the same circuit or in a nearby circuit. It is measured in henrys.

The property of an electrical component , which opposes the flow of electric current. An inductor has the property of impedance, the opposition to the flow of electric current.

An energy phenomenon that occurs as an electric field changes strength or polarity. During this transition, changes in the field can cause an electrical current to flow in a nearby object. As it relates to ESD, a charged object such as a plastic tray can induce a current flow in an ESDS device without actually touching it. If the induced current is high enough, it can cause an ESD failure.

One cause of reactance. An electromagnetic phenomenon in which the expanding and collapsing of a magnetic field surrounding a conductor or device tends to impede changes in current. The effects of inductance become greater as frequencies increase. The basic unit for inductance is the henry.

The property of an electric circuit or device by which an electromotive force is induced in the circuit itself as the result of opposition to change in magnetic flux, or current flow.

That property of a circuit element which tends to oppose any change in the current flowing through it. The inductance for a given inductor is influenced by the core material, core shape and size, the turns count of the coil, and the shape of the coil. Inductors most often have their inductance values expressed in microHenries (Î¼H) or milliHenries (mH).

The characteristic of an electric circuit by which varying current in it produces a varying magnetic field which causes voltages in the same circuit or in a nearby circuit.

a property of a circuit that is the proportionality constant between the rate of change of the current in that circuit and the electric and magnetic field that this changing current produces.

Property of a circuit to oppose a change in current. The moving magnetic field produced by a change in current causes an induced voltage to oppose the original change.

The ability of a coil to store energy and oppose changes in current flowing through it. A function of the cross sectional area, number of turns of coil, length of coil, and core material.

The storage of electrical energy in a magnetic field, which creates opposition to a change in current--like electrical inertia. When varying current flows through a conductor (especially if coiled), a field of electromagnetic flux (EMF) is generated that will induce voltage in any nearby conductor (especially if coiled), as well as in the current carrying conductor itself. Inductance in a circuit creates a phase difference between the voltage and the current in that circuit, in which the voltage leads, or peaks before the amperage. The unit of inductance is the henry (h). (See EMF; Transformer) Inductive Load: Any electrical device that has inductance and requires a surge of power to start--especially those with inductive motors in them, such as power tools and traditional AC well pumps, which can require up to six times the power they need to run in order to start running. As opposed to a resistive load.

A changing current in a coil produces a changing magnetic flux. The changing magnetic flux results in an induced current flowing in the coil. The unit is a Henry. One Henry is the inductance of a circuit that produces a counter-force of 1 volt when the current flowing is changing at the rate of 1 amp per second.

The property of a circuit or circuit element that opposes a change in current flow, thus causing current changes to lag behind voltage changes. It is measured in henrys.

When electrical current passes through a wire, it generates a magnetic field around the wire. Likewise, a changing magnetic field will generate an electrical current in any wire passing through the field. This principle is known as inductance, and it's used frequently in electronics. All radio transmisson is based on inductance, for example. Motors, generators, and relays rely on the principle as well. More details

The natural property of an electrical circuit which opposes the rate of change or current, i.e., electrical intertia.

Inductance opposes a change in current in an electrical circuit. Alternating Current (AC) varies with time; electromotive force is generated to oppose the current flow. Electromotive force is defined as: Force that occurs due to the voltage produced by a magnetic field that is in opposition to the magnetic field that is around a coil. The voltage is induced in the coil when the magnetic field cuts the coil. Current moving through the coil forms a magnetic field around the coil. This magnetic field moves across the turns of the coil, which induces a second voltage, which builds a magnetic field opposing the course current. The induced voltage is counter electromotive force.

The magnitude of a magnetic field created by a circuit carrying a current. This can cause higher voltages in the circuit.

The property of an electric circuit whereby an electromotive force (emf) is induced in it by a change of current in itself or in a neighboring circuit. When a current changing at the rate of one ampere per second induces a voltage of 1 volt, the inductance of the circuit is 1 henry.

The property of a circuit that opposes any change in the current of that circuit.

Inductance (or electric inductance) is a measure of the amount of magnetic flux produced for a given electric current. The term was coined by Oliver Heaviside in February 1886. The SI unit of inductance is the henry (symbol: H), in honour of Joseph Henry.
