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.

Why capacitor used only in AC power system?
A capacitor is included in the circuit to act as a filter to reduce ripple voltage. ... filter circuitmay be built using two capacitors and an inductor: ...look at http://en.wikipedia.org/wiki/Reservoir_capacitor
Can you measure ac mains voltage with dc voltmeter or high dc voltage with ac meter?
You cant.
Is lightning AC or DC voltage?
Lightning is static electricity. It's a buildup of charge, and it is facilitated by charge separation. In that light, it is DC.
Can you connect an AC source in series to DC source - then what happens to the current under a steady state condition?
With an AC and a DC voltage source in series, the DC voltage can be added to the RMS value of the AC voltage to give the effective voltage.
Does a Cpacitor allow ac to pass through it?
no capacitor does not allow ac component .if allow then inductor allow dc component .
How do you convert 23 voltage DC to 230 Voltage AC?
How do you convert 23 voltage DC to 230 Voltage AC?
Why does an inductor block AC but allow DC?
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 the difference between coil inductor solenoid?
Physicall no difference.But inductor uses ac and solinoid uses dc.
Can you measure ac mains voltage with dc voltmeter or high dc voltage with ac meter?
You cant.
ABS sensor produce AC voltage or DC voltage?
AC !
Does an inductor blocks AC?
An inductor blocks AC while allowing DC because it resists a change in current. The equation of an inductor is ...di/dt = V/L... meaning that the rate of change of current is proportional to voltage and inversely proportional to inductance.If you apply DC across an inductor, it will stabilize to some current flow based on the maximum current available from the current / voltage source. In this mode, the inductor presents very low resistance, so it can be said that it allows DC to pass.If, however, you apply AC across an inductor, you need to consider its inductive reactance by integrating the above equation in terms of the circuit conditions. The equation for inductive reactance is ...XL = 2 pi F L... meaning that the inductive reactance is proportional to the frequency and to the inductance.Thus, the higher the frequency, the higher the reactance. Since reactance is a phasor measure of resistance, it can be thus said that an inductor will block AC.

megger are available in ac &dc

Is DC voltage and average voltage same?
no, dc volatage is a type of current direct current, ac is alternating current, average voltage could be any type of voltage ac or dc that maintains a constant rangeAnswerNo. A DC voltage is exactly equivalent to an AC rms-voltage. So, for example, 100 V (DC) is exactly equivalent to 100 V (AC rms). The average value of an AC waveform is zero.
