What is the factor of q3-q2 plus 2q-2?
q3-q2+2q-2 = (q-1)(q2+2) = (q-1)(q+2.5i)(q-2.5i)
How do you draw a Factor tree with 12q when q stands for a prime number?
12q 2,6q 2,2,3q 2,2,3,q
How do you factor 2q squared minus 10?
2(q^2 - 5) or 2(q - the square root of 5)(q + the square root of 5)
What is Q factor?
In physics and engineering the quality factor or Q factor is a dimensionless parameter that describes how under-damped an oscillator or resonator is, and characterizes a resonator's bandwidth relative to its center frequency.Q factor, a measurement of a resonant system's relative bandwidthQ factor (bicycles), the width between where a bicycle's pedals attach to the cranksQ factor (digital communications), a way of representing bit error rates in dB
Why all numbers other than square numbers have an even number of factors?
Consider a number k. Let m be the square root of k : since k is not a square number, m is not an integer and so m cannot be a factor of k.Suppose p is a factor of k and suppose p< m.Then k has another factor q such that k = p*q and since p < m, then q> m.Thus, for every factor smaller than the square root, there is another factor that is larger than the square root. That is, the factors come is distinct pairs and so there is an even number of factors.
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.
What is the reciprocal of the power factor?
impedance/resistance
The Q factor of a radio coil is?
if its an LCR circuit then Q=wL/R where W=angular frequency L=Inductance of the coil R=resistance of the coil
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.
What is the power factor of a coil?
Power factor is the cosine of the phase angle between voltage and current. In a purely resistive load, like a toaster, since the phase angle is zero, the power factor is 1. In a theoretically purely inductive or capacitive load, with the phase angle at 90 degrees, the power factor is 0. Power factor is also the ratio of apparent power versus true power, or watts versus volt-amperes.
Why should Q point be fixed?
Q in a coil is the ratio of inductance to resistance unless the dimensions or the material changes the Q remains the same a synonym for Q is efficiency no perfect coil exists RC oscillators are stable since Q is fixed
What is a LCR Q meter?
LCR meters measure inductance capacitance and resistance Q requires 2 at once and probably a frequency range you may care about q meter will probably have two readouts and you may be able to change from Q to power factor
What is a LCR Q-meter?
LCR meters measure inductance capacitance and resistance Q requires 2 at once and probably a frequency range you may care about q meter will probably have two readouts and you may be able to change from Q to power factor
What is coil span factor and distribution factor?
coil span or coil pitch is defind as the distance mesured in terms of armature slots(or armature conductors) between two sides of a coil.
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 quality factor for choke coil?
the quality factor for choke coil is impedence divided by resistance in a given circuit
What is q factor in rlc series circuit?
In a RLC series circuit the Q factor magnify the voltage to the circuit.
