Definition von reactance im Englisch Englisch wörterbuch
opposition to the change in flow of current in an alternating current circuit, due to inductance and capacitance; the imaginary part of the impedance
The opposition to a flow of current other than pure resistance Inductive reactance is the opposition to change of current in an inductance (coil of wire) Capacitive reactance is the opposition to change of voltage in a capacitor
opposition to the flow of electric current resulting from inductance and capacitance (rather than resistance)
Any force that opposes a change in current flow Coils produce inductive reactance that delays the flow of current Capacitors produce capacitive reactance that accelerates current flow Reactance is measured in ohms and affects the current and voltage relationships in AC circuits
The opposition to the flow of an alternating electrical current of a particular frequency due to capacitance and or inductance
The reactance of a circuit is equal to the component of the impressed electro-motive force at right angles to the current divided by the current, that is, the component of the impedance due to the self-inductance or capacity of the circuit
Opposition to the flow of electrical current which changes with the frequency of the current
The opposition offered an alternation electron flow by a capacitance or inductance The amount of such opposition varies with the frequency of the current The reactance of the capacitor decreases with an increase in frequency; the opposite occurs with an inductance Receptacle A contact device installed at the outlet for the connection of a single attachment plug
When applied to a pneumatic system such as the lungs, reactance is a mathematical expression of the combined effects of compliance, inertance and frequency
Opposition to changes in flow of alternating current Capacitive reactance is opposition in change from a capacitor, and inductive reactance is the opposition in change from a coil or other inductor
The opposition offered to the flow of alternating current by inductance or capacitance of a component or circuit
the "imaginary" component of impedance, or the resistance to AC signals at a certain frequency Capacitive reactance is equal to 1/(2*pi*f*C), and inductive reactance is equal to 2*pi*f*L The unit of reactance is the ohm
Technical term to describe voltage drop in an alternating current transmission line; analogous to resistance in a direct current transfer of power
The portion of the electrical impedance in an AC circuit that is not due to pure resistance Capacitive reactance causes impedance to rise as the signal frequency decreases, whereas the inductive reactance causes impedance to rise as the frequency increases
A component of impedance produced by either inductance or capacitance in an AC circuit
The influence of a coil of wire upon an alternating current passing through it, tending to choke or diminish the current, or the similar influence of a condenser; inductive resistance
Opposition to the flow of alternating current Capacitive reactance is the opposition offered by capacitors, and inductive reactance is the opposition offered by a coil or other inductance
A measure of the combined effects of capacitance and inductance on an alternating current The amount of such opposition varies with the frequency of the current The reactance of a capacitor decreases with an increase in frequency The opposite occurs with an inductance
A measure of a circuits opposition to the flow of AC electricity due to only the effects of capacitors and inductors, usually measured in ohms No net power is transferred to the reactance of a load
The property of an elelectical circuit element to resist changes in voltage or current Like resistance, it is measured in Ohms The reactance of a circuit changes with frequency Reactance also alters the phase relationship between current and voltage It applies to all time-variant signals See also: impedance, resistance, capacitive reactance
A negative emotional and cognitive reaction to a restriction of one's freedom that can be associated with medical regimens
Measure of the opposition that an electrical circuit or a part of a circuit presents to electric current (see electrical impedance) insofar as the current is varying or alternating. Steady electric currents flowing along conductors in one direction undergo opposition called electrical resistance, but no reactance. Reactance is present in addition to resistance when conductors carry alternating current. Reactance also occurs for short intervals when direct current is changing as it approaches or departs from steady flow (e.g., when switches are closed or opened). Reactance is of two types, inductive and capacitive. Inductive reactance is associated with the varying magnetic field that surrounds a wire or a coil carrying a current. Capacitive reactance is associated with the changing electric field between two conducting surfaces (plates) separated from each other by an insulating medium. The ohm is the unit of reactance
