What is reactance with example?
What is reactance with example?
Reactance, denoted X, is a form of opposition that electronic components exhibit to the passage of alternating current (alternating current) because of capacitance or inductance. In the case of a magnetic field, the reactance is inductive. In the case of an electric field, the reactance is capacitive.
What is an example of inductance?
So inductance is also a measure of the amount of electromotive force (voltage) generated for a given rate of change of current. For example, an inductor with an inductance of 1 henry produces an EMF of 1 volt when the current through the inductor changes at the rate of 1 ampere per second.
Where is inductive reactance found?
The inductive reactance is found directly from the expression XL = 2πfL. Once XL has been found at each frequency, Ohm’s law as stated in the equation I = V/XL can be used to find the current at each frequency.
What is the formula of inductive reactance?
Inductive reactance is defined as:(10-4)XL=_ωL=2πfLwhere XL is the inductive reactance, ω is the angular frequency, f is the frequency in Hertz, and L is the inductance.
What is reciprocal reactance?
(iii)Susceptance is the reciprocal of reactance offered by capacitance or inductance in an AC circuit.
What is inductive reactance units?
Inductive reactance is expressed in ohms. (The unit of frequency is hertz, and that of inductance is henry.)
What are the types of inductance?
Basic Electronics – Types of Inductors
- Air-core Inductor. The commonly seen inductor, with a simple winding is this air-Core Inductor.
- Iron-Core Inductor. These Inductors have Ferromagnetic materials, such as ferrite or iron, as the core material.
- Toroidal Inductors.
- Laminated Core Inductors.
- Powdered Iron Core Inductors.
What is inductance and inductive reactance?
Inductance is the property of a circuit to oppose any change in current and is measured in henries. Inductive reactance is a measure of how much the countering emf in the circuit will oppose current variations.
What is inductive reactance XL =?
The inductive reactance formula is: Inductive reactance(XL) : 2π f L. where f is the frequency of the alternating current measured in Hertz(hz) and L is the inductance measured in henry(h). It is proportional to the frequency of the current and hence inversely proportional to the Time. XL α f and XL α (1/T).
What is inductive reactance Class 12?
Inductive Reactance: The opposition offered by an inductor to the flow of alternating current through it is called the inductive reactance.
How do you find total inductive reactance?
Work out the answers using pencil and paper; redraw the circuit you are working on.
How do you increase inductive reactance?
Inductive reactance increases with increasing frequency. In other words, the higher the frequency, the more it opposes the AC flow of electrons.
What is inductance reactance?
Inductive reactance is a property exhibited by an inductor, and inductive reactance exists based on the fact that an electric current produces a magnetic field around it.
Does reactance increase with an increase in inductance?
The inductive reactance of an inductor increases as the frequency across it increases therefore inductive reactance is proportional to frequency ( XL α ƒ ) as the back emf generated in the inductor is equal to its inductance multiplied by the rate of change of current in the inductor.
