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 (XL) = ω L

Alternating emf in the circuit is:

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

EXPLANATION:

Inductive reactance = ω L

So option 4 is correct.
