Here, use Zt= Zl.Zc\ Zc+Zl and get answer.

When i calculated first my ans was 0.101
n now my ans is 3.2KHz
Let me expalin,
Fr = 1/[2*3.14*sqrt{(75*10^-3)(0.033*10^-6)}]
= 1/[2*3.14*sqrt{2.475*10^-9}]
=1/[2*3.14*4.975*10^-5]
=1/[3.124*10^-4]
n now my ans is 3.2KHz

Fr = 1/[2*3.14*sqrt{(75*10^-3)(0.033*10^-6)}]

=1/[2*3.14*4.975*10^-5]
=1/[3.124*10^-4]

First divide 75 on 1000 and .033 on 1000000, multiply both and simply take sqrt. Your answer will come correct. Don't you worry. @Mr.Hussain.

There is significance for rw which is a series resistance of inductor.

F = 1/[2*pi*sqrt(L*C)].
F = 1/[2*3.14*sqrt(75*10^-3*0.033*10^-6)].
F = 3.2 Khz.
F = 1/[2*3.14*sqrt(75*10^-3*0.033*10^-6)].
F = 3.2 Khz.

Please anyone explain why series resonence formula is used in parallel circuit.

It's a parallel resonance circuit so, why you apply the formula of series resonance circuit?

Rw means resistance of inductor coil or winding.

Given 3.2 kHz is the right answer.
As we know that sqrt of 100 is 10 but sqrt of 10 will be 3.1.
So by changing the sqrt of given value 2.475 as 24.75 will different.
