An inductor blocks AC but it allows DC . Why ? and How ?

A capacitor blocks D.C, but allows A.C to pass through it. Explain why.

Assertion : A capacitor block DC but allows AC. Reason : Capacitive reactance, Xc=(1)/(2pifC). for d.c. f=0,thereforeX_(c)=oo " for a.c. X_(c)=alpha(1)/(f)

An inductor 20 m H , a capacitor 50 mu F and a resistor 40 are connected in series across a source of emf V=10 sin 340 t. The power loss in A.C. circuit is

An inductor 20 mH , a capacitor 50 muF and a resistor 40 Omega are connected in series across a source of emf v = 10 sin 340 t. The power loss in AC circuit is ………. .

If the circuit is connected to a high frequency supply (240 V, 10 kHz). Hence, explain the statement that at very high frequency, an inductor in a circuit nearly amounts to an open circuit. How does an inductor behave in a dc circuit after the steady state?

An inductor coil joined to a 6 V battery draws a steady current of 12 A . This coil is connected to a capacitor and an AC source of rms voltage 6 V in series. If the current in the circuit is in phase with the emf, find the rms current.

A resistance is connected to an AC source. If a capacitor is included in the series circuit, will the average power absorbed by the resistance increase or decrease? If an inductor of small inductance is also included in the series circuit, will the average power absorbed increase or decrease further?

Which of the following devices does not allow D.C. to pass through ?

An inductor- coil, a capacitor and an AC source of rms voltage 24 V are connected in series. By varying the frequency of the source, a maximum rms current of 6 A is observed. If this inductor coil is connected to a DC battery of emf 12 volt and internal resistance 4Omega , then current through it in steady state is
