Why an inductor is an easy path for d.c. and resistive path for a.c?

Show that a capacitor is an easy path for a.c. but a block for d.c. (i.e. offers infinite resistance for d.c.).

An inductor acts as a conductor for d.c., why?

What do you mean by inductive reactance, capacitive reactance and impedance? Show that a capacitor is a block for d.c., and an inductor, a block for a.c.

Derive the expression for the impedance of an a.c. circuit with an inductor ‘L’, capacitor ‘C’ and a resistor ‘R’ in series. What iscondition of resonance ?

An inductor L, a capacitor 20muF and a resistor 10 ohm are connected in series with an a.c. source of frequency 50 Hz. If the current is in phase with the voltage. Calculate the inductance of the inductor.

An a.c. voltage E = E_0 sin omegat is applied across a series combination of an inductor L, a capacitance C and a resistor R. Use the phasor diagram solution to obtain expressions for the impedance of the circuit.

A capacitor of 100 muF , a resistor of 20 Omega and an inductor of inductance L are connected in series with an a.c. source of frequency 50 Hz. Calculate the value of inductance L of the inductor, if phase angle between current and voltage is zero.
