Fr is inversely proportional to C.

It's simple,

Xl=xc is resonant frequency.
Xl>xc is resonant frequency decrease.
Xl<xc is resonant frequency increase i.e c decrease means xc increase xc=1/2πfc.

@Srinu wrote resonant fq = 1/r(root (L/C)).

But resonant fq = 1/r(root (LC)). I can't understand.

Because in resonance wL= 1/wC then, when L is increases then C is decreases and vice-versa.

xc=xl
1\wc=wl
1\w2lc=1
w2=1\lc
f=1\2*3.14root(l*c)

Fr=(1/R(root(L/C))). Hence as C decreases fr increases.
