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

@Sumeet.

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.

Rafiq said:   9 years ago
Current increases because it is inversely proportion to the inductive reactance.

I=v/Xl, so XL=6. 8fl, thats why frequency reducing current will be increased.

Abdul Rauff said:   1 decade ago
Xl = jwL = j*2*pi*f*L
so when f decreases ,Xl decreases and current increase

When frequency decrease indultance also decrease and so current increase.

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

If xl= 2p then it will increases.

Yes, You are right @Bhargav.
