Mell What is the meaning about reactance inductance?
the opposition of inductance to alternating current, equal to the product of the angular frequency of the current times the self-inductance. Symbol: XL.
What is inductive reactance state its formula?
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 happens inductive reactance?
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.
What is the difference between inductance and inductive reactance?
Inductance is the ability to create a voltage within a conductor or a nearby conductor by changing the current flow in that the first conductor. The larger the inductance the greater the voltage induced per change in current. Inductive reactance is an opposition to a change in current.
What is inductive reactance for DC?
Inductive Reactance against Frequency The slope shows that the “Inductive Reactance” of an inductor increases as the supply frequency across it increases. Then we can see that at DC an inductor has zero reactance (short-circuit), at high frequencies an inductor has infinite reactance (open-circuit).
What is called reactance?
In electric and electronic systems, reactance is the opposition of a circuit element to the flow of current due to that element’s inductance or capacitance. As frequency increases, inductive reactance also increases and capacitive reactance decreases.
What causes inductive reactance?
The magnetic field induces the voltage in the inductor which is always opposite in polarity to the voltage that produces it, i.e., applied voltage. This opposing voltage limits the current flowing through an inductor and it is called reactance (X). Since this reactance is caused due to inductance, it is called inductive reactance (X L).
What is the formula of the inductive reactance?
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).
What do you mean by inductive reactance?
Inductive reactance is associated with the magnetic field that surrounds a wire or a coil carrying a current. An alternating current in such a conductor, or inductor, sets up an alternating magnetic field that in turn affects the current in, and the voltage (potential difference) across, that part of the circuit.
How do you find total inductive reactance?
Inductive Reactance (X L) Calculations Work out the answers using pencil and paper; redraw the circuit you are working on. List the items of information you are given, and what you need to find for your answer. Once you have listed the information in step 2 (above), you will need to decide on which appropriate formula (or formulae) to use.
