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.

What is the impedance of a series circuit containing a resistor of 100 ohms and an inductor with an Xl equal to 80 ohms?

The resistance that an inductor poses to the flow of ac?
An inductor has two properties. The first is resistance(measured in ohms), which is due to the length, cross-sectional area, and resistivity of the conductor from which it is wound. The second is inductance (measured in henrys), which is due to the length of the inductor, its cross-sectional area, the number of turns, and the permeability of its core.The inductor's resistance limits the value of current flowing through the inductor. The inductor's inductance opposes any change in current.
What happens when dc supply is given to inductor?
The resulting maximum current is limited by the resistance of the inductor. As the current increases from zero to that maximum value, its expanding magnetic field induces a voltage into the inductor which opposes the rise in that current. So, instead of reaching its maximum value instantaneously, it takes some time -determined by the equation:time to maximum current = 5 L / R (seconds)where L = inductance of inductor in henrys, and R = resistance of inductor in ohms.
What would be the resonant frequency for a series RLC circuit with the following components a 1 k ohms resistor a 900 micro Henri inductor and a 0.014 micro farad capacitor?
44836.82577 Hz
Is 8 ohms good or bad resistance?
For an 8 ohm speaker, 8 ohms is perfect. "Good" and "bad" are relative to the application.

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
Is there no induced voltage in an inductor unless the current is changing?
In an ideal inductor, no, there is no voltage induced across an inductor unless the current in the inductor is changing. However, since there are no ideal inductors nor power supplies, eventually an inductor will draw a constant current, i.e. the limit of the power supply; and, since no inductor has zero ohms at equilibrium, that current will translate to voltage.
What value will appear on ohmmeter when we will check 100 uh microhenry inductor?
The reading will be very close to zero ohms.
How do you test resistance in a circuit?
With a meter that measures Ohms.

What is the definition of an inductive reactance?
Opposition to the flow of AC current produced by an inductor. Measured in Ohms and varies in direct proportion to frequency.
What is working principle of inductor?
A changing current through an inductor induces a voltage into the inductor, the direction of which always opposes the change in that current.So, in a d.c. circuit, an inductor will oppose (not prevent) any rise or fall in current, although the magnitude of that current will be determined by the resistance of that inductor, not by its inductance.In an a.c. circuit, because the current is continuously changing both in magnitude and in direction, it acts to continuously oppose the current due to its inductive reactance. Inductive reactance is proportional to the inductance of the inductor and the frequency of the supply. The vector sum of the inductive reactance of the inductor and the resistance of the inductor, is termed the impedance of the inductor. Inductive reactance, resistance, and impedance are each measured in ohms.
What is 8 ohms in hertz?
That is possibly the input impedance of a loudspeaker - not an impedance of an amplifier.

State three things which can affect the voltage in a circuit?
Ohms Law says that Voltage = Current * Ohms, so the twothings that can affect the voltage in a circuit are Current and Ohms. If have a non resistive impedance, i.e. a capacitor or inductor forming a reactance, then frequency can also affect the voltage but, mathematicaly, reactance is a frequency domain form of impedance, so my answer stands - Current and Ohms.
What is the inductive reactance of a 2 H inductor in a 60 Hz AC circuit?
The inductive reactance of a 15 Henry inductor at 60 Hz is about 5.7 KOhms. (2 pi f l)
