Inductive reactance unit

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 the unit of XL and XC?

The circuit consists of an inductive reactance XL=50Ω, capacitive reactance XC=50Ω and ohmic resistance R=10Ω. Calculate the impedance of the circuit and also potential difference across L and R.

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 state Its S.I. 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 impedance SI unit?

Impedance (symbol Z) is a measurement of a circuit's total resistance to current, or how much it obstructs the flow of charge. It's similar to resistance, but it also takes capacitance and inductance into account. Ohms are the unit of measurement for impedance (ohm).

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 the SI unit of reactance?

The S.I unit of capacitance is farad, but the S.I unit of capacitive reactance is ohms.

What is the symbol for inductive reactance?

Inductive Reactance which is given the symbol XL, is the property in an AC circuit which opposes the change in the current.

What is inductive unit?

The induction unit uses the ejection effect produced by the high-pressure primary air that flows through nozzles and sucks the interior (return) air, which is forced through heat exchangers that cool or heat it as required. The induction units are usually installed under a window or in an overhead location.

What is inductance and SI unit?

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).

What is the unit of capacitive and inductive reactance?

XL=2πfL, with f the frequency of the AC voltage source in hertz. Inductive reactance XL has units of ohms and is greatest at high frequencies. For capacitors, we find that when a sinusoidal voltage is applied to a capacitor, the voltage follows the current by one-fourth of a cycle, or by a 90∘ phase angle.

Why is it called inductive reactance?

Inductive Reactance: The opposition offered by an inductor to the flow of alternating current through it is called the inductive reactance.

Which unit is mho?

The siemens (symbolized S) is the Standard International (SI) unit of electrical conductance. The archaic term for this unit is the mho (ohm spelled backwards). Siemens are also used, when multiplied by imaginary numbers, to denote susceptance in alternating current (AC) and radio frequency (RF) applications.

What is unit of conductance?

siemens (S), unit of electrical conductance. In the case of direct current (DC), the conductance in siemens is the reciprocal of the resistance in ohms (S = amperes per volts); in the case of alternating current (AC), it is the reciprocal of the impedance in ohms.

What is reactance formula?

The formula for calculating the inductive reactance of a coil is: Inductive reactance, or XL. is a product of 2 times (pi), or 6.28, frequency of the ac current in hertz, and the inductance of the coil, in henries. XL. = 2x f x L.

What is XL and XC formula?

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 capacitance unit?

The unit of electrical capacitance is the farad (abbreviated F), named after the English physicist and chemist Michael Faraday. The capacitance C of a capacitor is the ratio of the charge Q stored in the capacitor to the applied dc voltage U: C = Q/U.

What does XC equal to?

Therefore, 90 in roman numerals is written as XC = 90.

What is LCR reactance?

In an LCR series circuit, the capacitive and inductance reactance have opposing effects. The capacitive reactance causes the current to lead the voltage, whereas the inductance reactance causes the current to lag the voltage.

What is reactance in RLC circuit?

The reactance of inductor L = XL = ωL and its impedance Zi = 0 + jωL = 0 + jXL. Thus, the impedance of an inductor is always imaginary, leading the resistor R by 90◦. Curve (a) in Figure 12.7 shows the variation of XL( = ΩL) with the frequency.
