Exact formula is calculated as;
XL=XC.
2*π*f*L=1/(2*π*f*C).
for frequency we can simply it as;
2*π* f^2 *L=1/2*π*C.
f=1/2*π*√(L*C).
XL=XC.
2*π*f*L=1/(2*π*f*C).
for frequency we can simply it as;
2*π* f^2 *L=1/2*π*C.
f=1/2*π*√(L*C).

What is the exact formula f = (1/2 * pi * sqrt(LC)) or f = 1/(2 * pi * sqrt(LC)?

At resonance Xc = XL.
i.e 4 1/(2*3.14*C*F) = 2*3.14*L*F.
F = 1/(2*3.14*sqrt(L*C)).
By substituting values we get F = 281 Hz.
i.e 4 1/(2*3.14*C*F) = 2*3.14*L*F.
F = 1/(2*3.14*sqrt(L*C)).
By substituting values we get F = 281 Hz.
