It is clear that at resonance frequency, XL=XC which means there is no reactance, because in coils current leads voltage and in capacitors current lags voltage. So if you lag and lead in the same rate, phase angle will be 0° degrees and we are dealing with resistive circuit. The only resistance we will see is the one of the winding in the coils.
Anyone explain that why the voltage is different than in the input, when is clearly open circuit?

At resonance XL=XC.
Now Output Voltage can be obtained by applying voltage divider rule.
Vout= (7/(7+33))*380mV = 66.5mV.

Vout= (7/(7+33))*380mV = 66.5mV.

Ya if inductor is connected then the resistor is connected in series. That only shown there.

At resonance xl=xc so by using current division rule find out the output voltage.

I think the symbol of R1 entered here is wrong. Please correct me, if I am wrong.

Here is Rw is the resistance of inductor or resistance it self?

What does Rw mean here. Is it resistance of wire or what?

I think resistance of the windings of the inductance.

AT RESONANCE X = 0 & Z = R 380*(7/(7+33)) = 66.5

Here Rw is internal resistance of inductor winding.
