What is the formula for inductive reactance in a circuit with a capacitor inductor and a resistor in a AC circuit?
to determine the total resistance, you add them vectorilly,first find the inductive reactance of the inductor by the following formula: 2 pi F L (2x3.14 x frequency in herts x inductance in henrys) next, consider the inductive reactance and the resistance as the two sides of a right triangle and the hippotanus would be the total impedance.(this combined ''resistance'' is called impedance.) to determine the total resistance, you add them vectorilly,first find the inductive reactance of the inductor by the following formula: 2 pi F L (2x3.14 x frequency in herts x inductance in henrys) next, consider the inductive reactance and the resistance as the two sides of a right triangle and the hippotanus would be the total impedance.(this combined ''resistance'' is called impedance.)
What circumstances is it possible for the rms current drawn from a certain source to have the same magnitude when an inductance is connected in series with a given impedance?
The same as what? when an inductor is connected in series with a resistor and a current passed through them, the voltages across the resistor and inductor are equal when the reactance is equal to the resistance: 2.pi.f.L = R
What is the impedance of an 8 Henry inductor at 120 Hz?
Use the formula: reactance equals 2.pi times frequency times inductance.
What is reactance of electric cable?
'Reactance' is the name given to the opposition to the flow of alternating current, due to the inductance of a load and the frequency of the supply voltage. It is measured in ohms.
An inductor is said to block ac but in transformer which is two inductors coupled together how can it allow an ac current?
While it is true that an inductor opposes the flow of an alternating current, it does not necessarily 'block it'. The quantity that opposes the flow of an AC current is the inductor's inductive reactance, expressed in ohms. Inductive reactance is proportional to the frequency of the supply voltage and, at 50 or 60 Hz, the reactance of a transformer's winding is relatively low (although very much higher than its resistance) and, while this acts to limit the amount of current flow, it certainly doesn't act to block that flow.
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 the inductive reactance of a 0.5 H inductor connected with a 1000 ohm resistor in an AC Circuit supplied with 48 VAC at 100 Hz?
The reactance of an inductor depends only on its inductance and the frequency.The voltage and any series components are irrelevant.Z = j 2 pi f L = j 2 pi (100) (0.5) = 314.16 ohmsreactive
If an inductor and a switch are connected in parallel through which the current will flow in an AC circuit?
A:The inductor does not allow ac signal to pass through. It blocks ac and passes dc. If the switch is open, then the ac signal wont pass. If the switch is closed, then the ac signal will pass through the switch.AnswerIt is incorrect to say that an inductor 'does not allow' the passage of an alternating current. An a.c. current will pass through an inductor, although the inductor will limit the value of that current due to the inductor's inductive reactance. Inductive reactance, which is expressed in ohms, is directly-proportional to the inductance of the inductor and to the frequency of the supply. The value of the current is determined by dividing the supply voltage by the inductive reactance of the inductor.If the switch is connected in parallel with the inductor, then closing the switch will apply a direct short circuit across the inductor, and the resulting short-circuit current will cause the circuit's protective device (fuse or circuit breaker) to operate.
If a coil has 100 microhenries inductance at 400 hertz what is it's reactance?
The reactance of an inductor is calculated as Xl = 2πfL, where Xl is the inductive reactance, f is the frequency, and L is the inductance. Substituting the given values of 100 microhenries for inductance and 400 Hz for frequency into the formula gives Xl = 2 * π * 400 * 100 * 10^-6 which equals approximately 251.3 ohms.
When are voltage and current out of phase?
Because the impedance of the inductor and capacitor is not a real resistance / has an imaginary value that causes voltage and current to be out of phase. An inductor's impedance is equivalent to j*w*L (j = i = imaginary number, w = frequency in radians, L = inductance), while a capacitor's impedance is 1/ (j*w*C). The 'j' causes the phase shift.
Why does the inductance of inductor varies with frequency?
It doesn't. the impedance of the inductor will, following the rule j*w*l, where l is inductance, w is frequency in radians and j is the imaginary number designating this a reactance, not resistance.
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)
Will an inductor work on DC?
An inductor cannot work in dc because the frequency is zero there by making the inductive reactance zero as a consequenceAnswerOf course an inductor can work in a d.c. circuit!
What circumstances is it possible for the rms current drawn from a certain source to have the same magnitude when an inductance is connected in series with a given impedance?
The same as what? when an inductor is connected in series with a resistor and a current passed through them, the voltages across the resistor and inductor are equal when the reactance is equal to the resistance: 2.pi.f.L = R
Why reactance does not oppose DC?
An ideal inductor does not oppose the steady flow of current because it has no resistance. But it opposes changes in the current and the voltage across the inductor is the rate of change of current (in amps/second) times the inductance in Henrys, which is how inductance is defined. So when a battery is connected across an inductor the initial rate of rise of the current is V/L amps/sec, where L is the inductance, and it continues to rise until limited by any resistance in the circuit.
What is the effect of inductance in the circuit?
Inductive reactance is proportional to frequency... XL = 2 pi f L ... so, the higher the frequency, the higher the reactance. At a sufficiently high frequency, the inductor would appear to be an open circuit. Note, however, that at very high frequencies, parasitic capacitance becomes a factor.
