The Q factor, or quality factor, of a coil can be measured by determining the ratio of its inductive reactance to its resistance at a specific frequency. This is typically done by applying an AC signal to the coil and measuring the voltage across it and the current flowing through it. The Q factor is calculated using the formula ( Q = \frac{X_L}{R} ), where ( X_L ) is the inductive reactance and ( R ) is the resistance. Alternatively, it can be measured using the bandwidth method, where the Q factor is derived from the resonant frequency and the bandwidth of the coil's response curve.

2(q^2 - 5) or 2(q - the square root of 5)(q + the square root of 5)
To find the image of point Q under a dilation centered at (0, 0) with a scale factor of 0.5, you multiply the coordinates of Q by 0.5. If Q has coordinates (x, y), the image of Q after dilation will be at (0.5x, 0.5y). This means that the new point will be half the distance from the origin compared to the original point Q.
A band-pass filter blocks or attenuates frequencies outside of a certain range, while it accepts frequencies from within that range. The range of frequencies it will accept is determined by its Q-factor. A filter with a high Q-factor will have a narrow range of accepted frequencies, whereas a filter with a low Q-factor will have a wide range of accepted frequencies.

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

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.
In a RLC series circuit the Q factor magnify the voltage to the circuit.
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.
yes ,Q factor is ratio of energy stored to energy dissipated

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.
The quality factor q affects the overall performance of the system by determining how efficiently energy is transferred and stored within the system. A higher quality factor q indicates better performance with less energy loss, while a lower quality factor q indicates poorer performance with more energy loss.
