Inductors can be measured in all three of the above:
When an the value of an inductor is given in henrys you are being given its "capacity" to store energy in a magnetic field.
Because the inductor is not made of a perfect conductor (one without resistance) it will inevitably has some associated resistance. This is the value that is being referred to if the value of ohms is given.
If an inductor is part of an AC (alternating current) circuit it will have a changing "resistance" (resistance as seen by the source) that is directly related to the frequency of the circuit. This is where the reactance value would be given. It equation is given as: 2*pi*f*L. Where f is frequency in hertz and L is the inductance given in henrys..
What else can I help you with?
Inductive reactance has a unit in?
Ohms, resistance in an inductor increases as the frequency of the AC signal increases, this "artificial resistance" is called impedence, and it is measured in ohms
If the resistance in ohms is higher than the voltage what does that mean?
Voltage is not measured in ohms. It is measured in volts.
What is Impedance for an RLC circuit in series?
1. The RLC series circuit is a very important example of a resonant circuit. It has a minimum of impedance Z=R at the resonant frequency, and the phase angle is equal to zero at resonance.AnswerThe impedance of an RLC circuit is the vector sum of the circuit's resistance, inductive reactance, and capacitive reactance -all of which are expressed in ohms. This applies whether the circuit is at resonance or not.
Why is circuit current reduced when a capacitors added to the circuit?
In the case of an a.c. circuit, capacitors oppose current because of their capactive reactance, expressed in ohms. Capacitive reactance is inversely-proportional to the capacitance of the capactor and to the frequency of the supply. So, adding a capacitor is series with an existing load will reduce the load current. On the other hand, adding a capacitor in parallel with an existing load will decrease the load current.
What is total impedance of a circuit when the resistance is 15k ohms and the capacitive reactance is 10k ohms?
You can write this as a complex number; the resistance is the real part, the reactance is the imaginary part (negative, for a capacitive reactance): 15 + j10 kilohms. ("j" is used instead of "i", to avoid confusion with current, which is symbolized by "i".) This is in rectangular coordinates; with a scientific calculator you can use rectangular --> polar conversion, to get the absolute value and the angle. To get just the absolute value, use Pythagoras' Theorem, which in this case gives about 18 kilohms.You can write this as a complex number; the resistance is the real part, the reactance is the imaginary part (negative, for a capacitive reactance): 15 + j10 kilohms.

Reactance in inductors and capacitors is expressed in which unit of measure?
ohm
What is the reason that capacitive reactance measured in ohms?
Because it is. Capacitive reactance is a form of resistance, along with inductive reactance. All are measured in ohms.
If an inductor measures 75 ohms will it still be good?
Inductors are not categorized in ohms. Inductors are categorized by their inductance measured in henrys. This is a measurement that can be measured by using a special meter. The only thing that the resistance will tell you is that the coil in not open circuited. So there is no real way to know if it is still good.
Why inductance value is negative?
Inductance is not negative. It is measured in henrys, and that is a positive value. Inductive reactance, however, is measured in ohms, and is commonly shown as negative to indicate that the current lags the voltage.
What is the unit of inductive reactance?
Inductive reactance, as well as capacitive reactance, is measured in ohms.
What is the units of inductance?
Inductive reactance, as well as capacitive reactance, is measured in ohms.
The unit of measure of inductive reactance?
The unit of measurement for inductive reactance (XL) is the ohm.
Can inductive reactance be in kilo ohm?
Yes. Inductive and capacitive reactance is measured in ohms, and it is entirely possible for reactance to be greater than 1,000, or even 1,000,000, ohms. It all depends on frequency.
What is difference between resistance and reactance while both are measured in ohms?
Resistance is constant no matter the frequency applied. Reactance varies depending on the frequency of the power applied to it.
What is the unit of measurement of inductive reactance?
Reactance is measured in ohms. By convention inductance produces a positive reactance while capacitance has a negative reatance. This is a convention that is consistent with a time-dependecy of exp(+jwt).
Inductive reactance has a unit in?
Ohms, resistance in an inductor increases as the frequency of the AC signal increases, this "artificial resistance" is called impedence, and it is measured in ohms
A series RL circuit contains two resistors and two inductors The resistors are 33 ohms and 47 ohms The inductors have inductive reactances of 60 ohms and 30 ohms When calculating the circuit val?
The total DC resistance is (33+47) = 80 ohms.The total reactance is j(60+30) = j90 ohms.The total impedance of the string is [ 80 + j90 ] ohms,= 120.4 ohms at a phase angle of 48.37 degrees (both numbers rounded).
