The circuit symbol of inductor is
Functions of inductor
the inductor (or) a reactor is a passive electrical component that can store energy in a magnetic field created by the electric current passed through it
How is it measured..??
the measure of inductors is designed in the unit called Henry
The value of inductors depends on what..??
an inductor with an inductance of 1 Henry produces an EMF of 1 volt when the current through the inductor changes at the rate of 1 ampere per second. The number of loops, the size of each loop, and the material it is wrapped around all affect the inductance.
How value is represented in inductor..??
The table below provides common Inductor values found in the Surface Mount [SMD] package.
Inductor Values are in uH [10-6 Henry]. These are preferred values.

Inductors in series
the value of inductions in series as L=L1+L2+...
capacitors in parallel
the value of inductors in parallel as 1÷L = 1÷(L1+L2+...)
