|When frequency decrease indultance also decrease and so current increase.|
|Abdul Rauff said: (Dec 14, 2011)|
|Xl = jwL = j*2*pi*f*L
so when f decreases ,Xl decreases and current increase
|Md Jamshed Nausherwan said: (Mar 27, 2012)|
|I=v/Xl, so XL=6. 8fl, thats why frequency reducing current will be increased.|
|Sumeet Kumar said: (Apr 28, 2012)|
|In pure inductor
I=V/XL,whereXL is inductive reactance
As f decreases XL also decreases thus I(CURRENT) increases
|Vijay Krishna said: (Dec 21, 2012)|
|We know that as inductance decreases then current increases. Also
Since Xl=2*3014*l*f. As frequency decreases inductance also decreases.
|Muhammad Yaqub said: (Apr 5, 2013)|
|XL and current are inversely proportional, and XL=2pi fL so when frequency decreases current will increases because they are inversely proportional.|
|Upendra said: (Dec 2, 2014)|
|Sinusoidal signal means A.C source so impudence present in circuit so inductive reactance is inversely proportional to voltage and directly proportional to current then current increases.|
|Taniya said: (Feb 11, 2015)|
|We know that, inductance opposes the flow of current. Therefore if inductance decreases by decreasing frequency, then current will increase, since the opposition (inductance) has decreased.|
|Er.Pankaj Pandey said: (Feb 12, 2015)|
|We know that inductance is a function of frequency which is directly proportional. If f increase then inductance increase. But I is inversely proportional to inductance. So I will increase when f decrease.|
|Amit Patel said: (Jun 24, 2015)|
When the frequency is decrease than voltage is also decrease, so current will not be change.
|Dhiraj said: (Jul 24, 2015)|
|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.|
|Stuti said: (Feb 15, 2016)|
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.
|Rafiq said: (Sep 10, 2016)|
|Current increases because it is inversely proportion to the inductive reactance.|
|Raf said: (Sep 10, 2016)|
|@Taniya is right.|
|Bhargav said: (Dec 8, 2016)|
|Frequency decreased means time period increases. Hence voltage decreases. Therefore current decreases.|
|Albert said: (May 25, 2017)|
|Yes, You are right @Bhargav.|
|Kamlesh Yadav said: (Sep 8, 2017)|
|Here, f proportional to V/I.
Then f decreases with increases I.
|D Shwetha said: (Sep 8, 2018)|
Your explanation is good.
If Frequency decrease, I will increase.
|Shivu said: (Sep 22, 2019)|
|Current will remains the same, because inductor which opposes the change of current.|
|Abbas said: (Oct 5, 2020)|
|If xl= 2p then it will increases.|
