What is inductive reactance?
What is inductive reactance?
Definition: Inductive reactance is the opposition offered by the inductor in an AC circuit to the flow of ac current. It is represented by (XL) and measured in ohms (Ω). Inductive reactance is mostly low for lower frequencies and high for higher frequencies. It is, however, negligible for steady DC current.
What is inductive resistance and its SI unit?
Inductive reactance XL—It is the effective opposition offered by the inductor to the flow of current in the circuit. Its S.I. unit is ohm.The dimension of inductive reactance is [ML2T-3A-2]It can be expressed as XL = LW.
What is inductive and non inductive resistance?
Inductive Resistor: Any circuit in which a change in the current is accompanied by a change in the flow and thus the induced EMF is referred to as inductive. Therefore no EMF is induced in the coil and the coil has no inductance. A non-inductive resistor can be used to replace an inductive resistor.
What is inductive and capacitive resistance?
If the reactance releases energy in the form of a magnetic field, it is called inductive reactance whereas if the reactance releases energy in the form of an electric field, it is called capacitive reactance.
What is inductive reactance SI unit?
Inductive reactance is denoted as XL. The SI unit is the ohm. The formula for reactance is given as. XL = 2πfL.
What is inductive resistance and unit and dimension?
In an inductive circuit, the self-induced emf opposes the growth as well as decay of current. The dimensions of inductive reactance are [ML2T-3I -2] and its SI unit is the ohm (Ω).
What is inductive reactance Class 12?
Hint: Inductive reactance is the opposition offered by an inductor in an alternating current circuit to the flow of alternating current. Unlike resistance, Inductive reactance can vary with the frequency of the input voltage. In an inductive circuit, the current lags the voltage by a phase difference of ninety degrees.
What is the formula for inductive resistance?
The formula for calculating the inductive reactance of a coil is: inductive reactance, or XL, is the product of 2 times p (pi), or 6.28, the frequency of the ac current, in hertz, and the inductance of the coil, in henries. XL =2p x f x L.
What is non inductive resistance?
A non-inductive resistance is a resistance which has no inductance (no opposition to changes in current flowing through it). Such resistance is important at high (radio) frequencies, as well as in high-speed logic (digital) circuits.
What is the difference between inductive and non inductive?
A non-inductive resistor can be used to replace an inductive resistor, but that might not be a realistic goal. Inductive resistors are typically cheaper to construct and are more commonly made with higher power ratings.
What is inductive and capacitive reactance?
The reactance is inductive if it releases energy in the form of a magnetic field. And the reactance is capacitive if it releases energy in the form of an electric field. As frequency increases, capacitive reactance decreases, and inductive reactance increases.
What is inductive and resistive load?
Basics, Electrical. The main difference between Resistive Load and Inductive Load is resistive load converts the electrical energy into heat whereas the inductive load converts the electrical energy into magnetic energy. There are ao many differences between inductive load and resistive are available.
