Inductive reactance is equal to?

CONCEPT:

• The device which stores magnetic energy in a magnetic field is called an inductor.
• A circuit that has the only inductor is known as a purely inductive circuit.

• Inductive reactance: The resistance offered to the flow of current by an inductor is known as inductive reactance.
  • It is represented by XL.
• Inductive reactance (X_L) = ω L

Alternating emf in the circuit is:

\(e={{e}_{o}}\sin \omega t\)

Where e0 = maximum potential, ω = angular frequency and t = time

EXPLANATION:

Inductive reactance = ω L

So option 4 is correct.
