Inductance is inductance, and is not a function of frequency. Frequency affects reactance, and ultimately impedance, not inductance.

What is the change in current when frequency changes from 8 khz to 400hz?
That depends on the circuit. For a pure resistive circuit (no inductance and capacitance), the frequency will have no effect on the current.
How reactance of inductors depends on frequency?
actually, inductance is directly proptional to the frequency according to the formula , so if frequency is more, then inductance is also more and vice versa
How would you wind a coil which has a resistance but essentially no inductance?
I wouldn't. I doubt this is possible. Wire, by definition will have inductance. The inductance will increase as the frequency increases, so I guess you could specify a frequency that is extremely low to use the coil at.
What will be the inductance in inductive circuit at low frequency?
The inductance doesn't change, but the impedance (equivalent to resistance) will be very low.
The resonance frequency of 1200 What is the resonance frequency if the inductance L is doubled?
1200/sqrt(2) = 848.5 (rounded)

Inserting a soft iron core into a coil has what effect on the inductance of a coil?
increase inductance
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 parasitic inductance of capacitor?
A: PARASITIC means like a parasite is there to offset the actual circuitry it can be inductance and/or capacitance A capacitor is usually wound in a coil this coil if frequency is hi enough will behave as a small coil has been added to the circuit. Hi frequency PWM capacitors have indeed four lead to reduce not eliminate this inductance
The resonance frequency of 1200 What is the resonance frequency if the inductance L is doubled?
1200/sqrt(2) = 848.5 (rounded)
What is the total inductance of two inductors in series?
Inductance in series is the sum of the individual inductances.
What is the effect of inductance in high frequency circuits?
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.
What is inductive reactance-?
There is no such term as 'inductance reactance'; the correct term is 'inductive reactance'. This is the opposition to the flow of a.c. current, due to the inductance of the load, and the frequency of the supply, and is measured in ohms.Inductive reactance is directly proportional to both the supply frequency and the load's inductance.
What is the total inductance of two inductors connected in series?
Inductance in series is the sum of the individual inductances.
