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.
What is the reciprocal of the power factor?
impedance/resistance
What is Q factor of a coil?
The Q factor of a coil, sometimes called the unloaded Q factor, is the ratio of the energy stored in the coil to the energy dissipated in the resistance of the wire.
Is Q factor ratio of energy stored to energy dissipated?
yes ,Q factor is ratio of energy stored to energy dissipated
What is the importance of the quality factor Q of a tuned amplifier?
If quality factor is greater then bandwidth will also greater
What is q factor in rlc series circuit?
In a RLC series circuit the Q factor magnify the voltage to the circuit.
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.
Effect of q factor on maxwell inductance bridge?
the bridge is preferably balanced by capacitor parallel attached resistance value. so, q factor of the inductor is given by w L / C at balance condition. q-value is low prefer

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 resonant frequency of parallel RLC circuit of R 4.7 k ohm L 2 micro Henry and c30pf?
The resonant frequency of 2 µH and 30 pF is 1 / 2 pi(LC)-0.5, or 20.5 MHz. The 4.7 K Ohm only affects Q Value, or ring time.
Q factor of low pass filter?
The Q factor is describing how sharp the dropoff of the filter is relative to the pass band. Wikipedia has a decent writeup on Q factor. The more components you use to make the filter, and the lower the cutoff frequency, the higher the Q will be.
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.
Is Q factor ratio of energy stored to energy dissipated?
yes ,Q factor is ratio of energy stored to energy dissipated
