What is the behavior of RC RL series circuit?
The series circuit described (if understood correctly) is a series tank circuit. It is a tuned circuit. The C and the L are capacitance and inductance, respectively, and they are said to be in series. What that translates into is that as an AC signal passes through them, they "ring" electronically (they oscillate) a certain amount depending on the frequency of the signal that is put in. Based on the C and the L, there will be one frequency that the circuit will like to run at, and this will be the resonant frequency (fo) of the series tank circuit. A maximum amount of oscillation can be expected at fo, and the tank is tuned for that frequency. But what if a signal is above or below fo? Signals above and below fo will not cause as much oscillation as the one right at fo. And the farther from fo they are, the less oscillation they will cause. If we graph the output (eo) of a stage (with frequency on the x-axis and gain on the y-axis) that has this kind of tuned circuit in it, we'll see a sharp peak at fo and a general falling off on either side. The farther from fo the input signal is, the less gain. This is true for signals both above and below fo. There is a slight difference in response as regards the slope of the flanks of that peak. The lower frequencies will fall off "forever" but the higher ones will fall of about the same as the lower ones to a point and then will not suffer much more attenuation. That's because at frequencies above fo, the circuit will have stronger capacitive characteristics, and the higher fequency signals will be coupled through. A graph of this circuit can be seen by using the link provided. There is also a link to the Wikipedia article on the RLC circuit from which this graph came. Lastly, the amount of R in the RLC circuit will determine the quality factor (Q) of the circuit. The quality determines how high and how wide the peak on our graph will be. Higher R means less quality. Lower R will result in higher Q. The higher Q circuit will have a higher and sharper peak. The lower Q circuit will have a lower but wider peak. The quality is a determinant in bandpass. Lower Q circuits will have higher (broader or wider) bandpass.

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 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 the Q factor in RLC circuit?
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.
Why there's high voltage at series rlc resonant frequency?
With a series RLC circuit the same current goes through all three components. The reactance of the capacitor and inductor are equal and opposite at the resonant frequency, so they cancel out and the supply voltage appears across the resistor. This means that the current is at its maximum, but that current, flowing through the inductor and the capacitor, produces a voltage across each that is equal to the current times the reactance. The voltage magnification is the 'Q factor', equal to the reactance divided by the resistance.
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.
How do you improve Q factor?
Minimize circuit resistance.
In resonant circuit large q factor means?
Sharp tuning the bigger the Q the sharper the response
What is the bandwidth of a circuit with a frequency of 5MHz and a q factor of 250?
I think it might be 20KHz. Q= frequency over bandwidth

Explain Why high Quality factor is needed in RLC Circuits?
the higher the Q the narrower the bandpass or band-rejection. however high Q is not always desirable. for example in receiver IF stages too high a Q will filter out some of the needed modulation bandwidth, destroying signal information.
What is a scientific word for q?
Q is often used to connote "electric charge".The Q factor of tuned circuits is a measure of "quality factor". It is a measure of how well the tuned circuit selects wanted frequencies and rejects the unwanted.
Is it possible to have a voltage drop across the energy storage element greater than the supply in series RLC circuit?
If, by 'storage element', you are are referring to the inductive and capacitive components (?), then the answer is yes. The voltage drop across these components is given by:VL = I XLVC = I XCIn fact, at resonance, if the resistance is low, then VLand VC can be very much higher than the supply voltage.
