What is the real usage or purpose of a capacitor or a
inductor in electrical network?.I expect a explanations
on the basis of electron flow

RE: caapcitors anad inductors
Capacitors try to keep the voltage constant
Inductor try to keep the current constant
By combining the two one can make filters, and oscillators.
RE: caapcitors anad inductors
Capacitors store energy by acquiring a charge called Q for which a capacitance C will yield a voltage V. The relationship between them is Q = C x V for which the stored energy is ½ x C x V².
Inductors store energy by acquiring a current flow I for which the product of voltage V and time T equals the inductance L times the current I. The stored energy in an inductor is ½ x L x I².
In the absense of resistive energy loss, an inductance and a capacitance connected together can transfer some quantity of stored energy back and forth between themselves over and over again. The number of times per second that this happens is called their resonant frequency.
Good luck.

RE: caapcitors anad inductors
The cap stores the energy as electrical, the inductor as
magnetic field.
When the voltage/current ends, the voltage/current is restored from the energy stored in the field until the field collapses.
