It is related to damping in the circuit using a resistor.
Q is inversely proportional to the resistor(R).
So if the value of resistance is high, there is a greater damping and the value of Q will be low.
if resistance is low, there is small damping and Q will be high.
when Q is high(low damping) the graph of voltage across resistor against frequency will be sharp at resonance and the bandwidth will be small
when Q is low(high damping) thee graph will be less sharp as the bandwidth will be large.
Go do some research on the graphs and the formula of Q factor to understand it better.

Reduce Q factor in parallel RLC?
In general, the way to reduce effective Q in a parallel RLC circuit is to reduce the value of R.
What is Power factor of series RLC circuit under resonance?
The power factor of an RLC circuit under resonance is 1. Explaination:- Power factor of an RLC circiut is given by=R/|Z| For a resonant circiut,|Z|=R (Because reactive components are zero in resonance) . . .Power factor=R/R=1.
Does resonant frequency of RLC series circuit depends on Resistance?
No, the resonant frequency of a RLC series circuit is only dependant on L and C. R will be the impedance of the circuit at resonance.
Why LCR series circuit is called acceptor circuit?
Answer:A given combination of R,L and C in series allows the current to flow in a certain frequency range only.For this reason it is known as an acceptor circuit i.e.,it accepts some specific frequencies....
Does the impedance of a parallel RLC circuit equal to the value of the resistor?
No. You have to consider the inductor and the capacitor. Impedance of RLC circuit is equal to to the Value of Resistor Only AND Only on Resonate frequency. otherwise u have to cnsider resistance inductance and capacitance together in series.

In a RLC series circuit the Q factor magnify the voltage to the circuit.

What is the unit of quality factor of RLC series circuit?
The selectivity or sharpness of series resonant circuit is measured by quality factor or Q factor.It is defined as the ratio of the voltage across the coil or capcitor to the applied voltage.In other words it refers to the sharpness of tuning at resonance. Q = voltage across L or C ( in volts) / applied voltage ( in volts ) Q = 1/ R * ( L/C)^ 0.5 Q is just a mere number having values between 10 to 100 for normal frequencies.So it has no unit. Circuit with high Q values would respond to a very narrow frequency range and vice versa.Thus a circuit with high Q value is sharply tuned while a circuit with low Q value has a flat resonance.Q factor can be increased by having a coil of large inductance but of small ohmic resistance.
What is RLC throughput?
RLC is a type of electrical circuit that involves a resistor, an inductor and a capacitor. The throughput is the amount of energy travelling through the circuit.
Do you expect angle in rlc series circuit to be a constant?
The phase shift angle of an RLC circuit is constant for a constant frequency, but changes with different frequencies.The phase angle of the AC in the RLC circuit is however continuously changing. Otherwise it wouldn't be AC.
Does resonant frequency of RLC series circuit depends on Resistance?
No, the resonant frequency of a RLC series circuit is only dependant on L and C. R will be the impedance of the circuit at resonance.
What is the Q factor in electrical and electronics engineering?
Q is the general idea of component quality, mainly in AC circuits. It is equal to reactance divided by resistance. The Q factor of an entire circuit can also be computed the same way. In general, adding resistance decreases the circuit or component Q. The "Q" factor is a empirical number to imply the acuteness of a circuit to discriminate surrounding influences and act on the Q of the circuit. The higher the Q THE SHARPER THE RESPONSE.
Condition of resonance in RLC circuit?
XL=Xc is the resonance condition for an RLC circuit
How do you improve Q factor?
Minimize circuit resistance.
What are the types of electric circuit?
Rl,rc,rlc
