Inductive Resistance Formula
Inductive resistance formula
Inductive reactance is the resistance offered by the inductive circuit. It is the opposition to a changing current flow offered by an inductor. The SI unit for it is Ohm(Ω). The inductive reactance formula is: Inductive reactance(XL) : 2π f L.
What is the SI unit of inductive resistance?
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).
What is inductive reactance XL?
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 resistance measured in?
As the current and voltage within an inductor are 90° out of phase with each other (current lags the voltage), inductive reactance and resistance cannot be directly added. The resultant combination of resistance and inductive reactance is referred to as impedance and this is again measured in ohms.
What is the symbol for inductive resistance?
Inductive reactance is the resistance faced by the current flow in the inductor when AC voltage is supplied. Its units are similar to units of resistance. The symbol of inductive reactance is “XL“.
What is inductive reactance SI unit?
Inductive reactance is denoted as XL. The SI unit is the ohm.
How do you calculate XC and XL?
This resultant is called REACTANCE; it is represented by the symbol X; and expressed by the equation X = XL − XC or X = XC − X L. Thus, if a circuit contains 50 ohms of inductive reactance and 25 ohms of capacitive reactance in series, the net reactance, or X, is 50 ohms − 25 ohms, or 25 ohms of inductive reactance.
What is XC formula?
Capacitive reactance is defined as:(10-1)Xc=1/ωC=1/2πfCwhere XC is the capacitive reactance, ω is the angular frequency, f is the frequency in Hertz, and C is the capacitance.
What is XL and XC in RLC circuit?
In a series RLC circuit at resonance, the two reactances, XL and XC are equal and canceling. In addition, the two voltages representing VL and VC are also opposite and equal in value, thereby canceling each other out.
What is the unit of inductive?
The SI unit of inductance is Henry abbreviated as 'H'. It is defined as the measure of electric current changes at one ampere per second, resulting in an electromotive force of one volt across the inductor. Henry is a derived unit based on some 7 base SI units like metre (m), second (s), kilogram (kg), and ampere (A).
How is induction calculated?
L = μN2A/l
- L = Inductance (H),
- μ = Permeability (Wb/Am),
- N = The coil's number of turns,
- A = The coil's circumference,
- l = Length of coil (m).
What is reactance formula?
Reactance Formula The total reactance (X) is equal to the difference between the two: Total reactance, X = XL. – XC. a.
What is the inductive resistance for DC?
The inductive reactance for an inductor is XL = ωL. For DC input, i.e. for ω = 0 rad/sec, the resistance/reactance offered by the inductor will be 0 Ω.
How do you calculate inductive and capacitive reactance?
This resultant is called REACTANCE; it is represented by the symbol X; and expressed by the equation X = XL − XC or X = XC − X L. Thus, if a circuit contains 50 ohms of inductive reactance and 25 ohms of capacitive reactance in series, the net reactance, or X, is 50 ohms − 25 ohms, or 25 ohms of inductive reactance.
Why is L used for inductance?
The symbol L for inductance was chosen to honor Heinrich Lenz (1804–1865), whose pioneering work in electromagnetic induction was instrumental in the development of the final theory.
Why is the unit of inductive reactance is ohm?
The inductive reactance is directly proportional to frequency. The unit of Inductive reactance is Ohm. The capacitive reactance is inversely proportional to the frequency. The unit of Capacitive reactance is Ohm.
What is inductive reactance and write its formula?
Inductive Reactance: The opposition offered by an inductor to the flow of alternating current through it is called the inductive reactance. It is denoted by XL. Its value is XL. =ωL=2πfL where.
What is XL and XC in physics?
There are two types of reactance: capacitive reactance (Xc) and inductive reactance (XL). The total reactance (X) is the difference between the two: Total Reactance, X = XL - Xc.
What is the unit of XC?
The unit of Capacitive Reactance Xc is Ohm.
What is XL in RL circuit?
In series LR circuit XL = R and power factor of the circuit is P1 when capacitor with capacitance C such that XL=XC is put in series, the power factor becomes P2 calculate P1P2.
