What is the difference between Resistance , reactance and inductance

What is the difference between Resistance , reactance and inductance

Resistance is the term which  oppose the  flow of current.Usually denoted by R.
Resistance is depend on material.
Reluctance is occure in ac power which oppose the flow of current in capacitor and inductor. reactance is not applicable in DC circuit.

There are two types of Reactance these are Inductive Reactance and Capacitive Reactance.

1) Inductive Reactance.
 When AC current flow through an Inductanace a back Emf or voltage is devloped opposing any change in the initial current.this opposition to flow of current is called inductive reactanance.

2) Capacitive reactance
When an Ac current flow through an capacitance a oppsing in intial voltage is occur this oppsing prperty is called Capacitive reactance.



For capacitors X=1/(2ΠfC); where f is the frequency,C is the capacitance.
For inductors X= 2ΠfL; where f is the frequency,:L is the inductance.
Impedance is the sum of the resistance and reactance of a circuit
denoted by Z=R+jX (for primarily inductive cirucits) or Z=R-jX (for primarily capacitive circuits).
