Electronics - RLC Circuits and Resonance - Discussion

Why you didn't consider the capacitor and inductor?

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.

R1 represents the resistance of the inductor.

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?

I can't get it please give me a clear explanation.
