Explanation & Answer

Thank you for the opportunity to help you with your question!
Inductive reactance: XL = 2*pi*f*L
It can be seen that the inductive reactance varies directly with frequency.
Therefore, if the frequency is decreased by a factor of 4, the inductive reactance will also decrease by a factor of 4.
Please let me know if you need any clarification. I'm always happy to answer your questions.
