if its an LCR circuit then
Q=wL/R
where
W=angular frequency
L=Inductance of the coil
R=resistance of the coil
Q Radio was created on 2008-06-02.
If you mean the radio communication alphabet, Q is Quebec
its a song by Luke Doucet specifically for Q
A synchronous generator is operating at lagging power factor (positive P & Q) when it is supplying P & Q to the system. P & Q are positive which means that they are flowing away from the bus where the generator is connected (overexcited case). On the other hand, it is operating at leading power factor when it is supplying P and absorbing Q. The sign of Q is negative which means that it is flowing towards the generator bus (underexcited case).

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.
impedance/resistance
The Q factor (quality factor) of a coil is a measure of its efficiency in storing energy and transferring energy to a load. It is calculated as the ratio of the reactance of the coil to its resistance. A higher Q factor indicates lower energy losses in the coil.
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.
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.

When ( Q ) decreases in a coil-pits oscillator, the frequency of oscillation increases. This is because the quality factor, ( Q ), is inversely proportional to the bandwidth of the oscillator. A lower ( Q ) value means a wider bandwidth, resulting in a higher frequency of oscillation.
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
The Radio Factor was created in 2002.
The Radio Factor ended in 2009.
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.
RF (Radio Frequency Coil) is a coil, which is designed to resonate at a frequency some where in the radio spectrum frequency. See L C Circuit Link Below.
