- 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:
\(e={{e}_{o}}\sin \omega t\)
Where e0 = maximum potential, ω = angular frequency and t = time
EXPLANATION:
Inductive reactance = ω L
So option 4 is correct.
