Frequency response of R-L-C series Circuit 
If the value of C in a series RLC circuit is decreased,the resonant frequency,
A series resonant circuit is commonly called a tank circuit
In a series RLC circuit that is operating above resonant frequency,the current,
In a series RLC circuit the phase difference between the current in the Inductor and in the resistor (in Degree) is,
In a series RLC circuit the phase difference between the current in the capacitor and in the inductor(in Degree) is,
