Given information

The Q-factor can be defined as the ratio of the voltage across the capacitor (or inductor) to the voltage across the resistor at resonance.

Q factor is given by the equation  

Step-by-step explanation

Step 1.

Q factor is given by the equation 

   

Where I is the current through the circuit , that is through resistor, capacitor and inductor. They are in series so the current through them are same.

is the inductive reactant 

R is the resistance .

Inductive reactance  

is the angular frequency =  

The resonant frequency
