You seem to be mixing up your terminology. There is no such thing as 'self-capacitance of an inductor'! If you know the frequency and equivalent capacitance for two capacitors, then you can find the equivalent capacitive reactance of the capacitors, but that's not what you seem to be asking! I suggest you rephrase the question.
An oscillator has a tuned circuit (inductance+capacitance) to determine the frequency. When the inductor is tapped to give the required phase-shift for oscillation it is a Hartley oscillator. When the capacitance is tapped it is a Colpitts.
Inductor impedance is given by jwL, where w=2*pi*frequency. Therefore as the frequency increases the impedance of the inductor increases, causing a larger current flow and a larger power dissipation across the inductor
Inductors are low pass devices, they conduct most easily at low frequencies. DC is the limiting case for low frequency AC: i.e. DC is the lowest possible AC frequency, zero Hz and thus conducts best through an inductor. Capacitors are high pass devices, they conduct most easily at high frequencies. Infinite frequency AC is the limiting case for high frequency AC. Infinity Hz would conduct best through a capacitor.
Inductors and capacitors are called reactive elements in electric circuits.these reactive elements also offer resistance in the circuit termed as reactancefor inductor it is wL (-j)for capacitor i is 1/wC (j)where L,C and w are inductance , capacitance and frequency of the AC source respectivelywhen clubbed with resistance the the resultant of the resistance and reactance gives us the impedance of a circuitif the impeadence(R=0) of the circuit is of inductor only then these are called as purely inductive circuitsif the impedence of the circuit is dominated by inductor ( wL > 1/wC ) even though the circuit has resistance and capacitor then these circuits are called inductive circuits
a transformer or inductor or capacitor does not change frequency frequency is controlled at the generating station with the speed of the motor or turbine the number of phases will not make a difference an inductor or capacitor can shift phase up to 90 degrees you can make 3 phase power from single phase power with inductors capacitors and transformers
Capacitors and inductors can be designed and used at higher frequencies. It is just harder to do so, because one has to consider parasitic capacitance and inductance. As an example, at a high enough frequency, even a simple piece of wire is an inductor, and it has capacitance relative to itself and to other wires.
The impedance of a component (inductor or capacitor) will change with frequency - resistor impedances will not. Inductor impedance - j*w*L Capacitor impedance - 1/(j*w*C) L = inductance, C = capacitance, j = i = imaginary number, w = frequency in radians The actual inductance and capacitance does not change with frequency, only the impedance.

A Colpitts oscillator is the electrical dual of a Hartley oscillator. In the Colpitts circuit, two capacitors and one inductor determine the frequency of oscillation. The feedback needed for oscillation is taken from a voltage divider made by the two capacitors, where in the Hartley circuit the feedback is taken from a voltage divider made by two inductors (or a tapped single inductor). (Note: the capacitor can be a variable device by using a varactor). Oscillation frequency The ideal frequency of oscillation for the circuit is given by the equation: where the series combination of C1 and C2 creates the effective capacitance of the LC tank. Real circuits will oscillate at a slightly lower frequency due to junction capacitances of the transistor and possibly other stray capacitances
The Maxwell bridge measures capacitance or inductance by balancing the unknown capacitor or inductor against known inductors or capacitors, with known resistors. In order to balance a bridge, there must be zero voltage across it. As a result, the vector for the capacitance leg must be exactly 180 degrees opposite, and of equal length, to the vector for the inductance leg.
The inductance of an inductor is the capacity of the inductor to induce electric flux. The capacitance of a capacitor is the capacity of the capacitor to store charges. THE IMPEDANCE OF A CIRCUIT IS THE TOTAL OPPOSITION OFFERED TO THE FLOW OF ELECTRIC CURRENT.
Inductor impedance is given by jwL, where w=2*pi*frequency. Therefore as the frequency increases the impedance of the inductor increases, causing a larger current flow and a larger power dissipation across the inductor
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.

The resistance of an inductor is generally referred to as the series resistance, sometimes noted as RL. Note that resistance is a DC measurement and that an "ideal" textbook inductor has an RL of 0. The reactance of an inductor is an AC measurement which measures the reaction of a component's current flow to an alternating voltage and is frequency dependent and directly proportional to the inductor's inductance, measured in Henrie's. The impedance is most commonly used when talking about inductors or capacitors and is a combination of resistance and reactance.
