When the frequency decreases, means AC is converted to DC, the inductor act as short circuit in DC. That's the reason when frequency reduces current increase.

We know,
XL = 2f*3.14l.
So if frequency decrease then XL also decease by which opposition of current also decrease and more current flow therefore current increase.
XL = 2f*3.14l.
So if frequency decrease then XL also decease by which opposition of current also decrease and more current flow therefore current increase.

Current increases because it is inversely proportion to the inductive reactance.

@Taniya is right.

Frequency decreased means time period increases. Hence voltage decreases. Therefore current decreases.

Here, f proportional to V/I.
Then f decreases with increases I.
Then f decreases with increases I.

@Sumeet.
Your explanation is good.
I=V/XL,
I=V/2πfL,
If Frequency decrease, I will increase.
Your explanation is good.
I=V/XL,
I=V/2πfL,
If Frequency decrease, I will increase.

Current will remains the same, because inductor which opposes the change of current.

If xl= 2p then it will increases.
