The amplitude of current in series LCR c...

The amplitude of current in series LCR circuit connected to an AC frequency "omega" is given by
`i_m = v_m/(sqrt(R^2+(X_L-X_C)^2)`
Where `X_L` and `X_C` are inductive and capacitative reactances respectively and `"v_m"` is amplitude of voltage. Starting fron this equation show that sharpness of resonance in the circuit is equal to the quality factor of the circuit.
