WHAT DOES Q FACTOR MEAN IN ENGLISH?
In physics and engineering the quality factor or Q factor is a dimensionless parameter that describes how under-damped an oscillator or resonator is, or equivalently, characterizes a resonator's bandwidth relative to its center frequency. Higher Q indicates a lower rate of energy loss relative to the stored energy of the resonator; the oscillations die out more slowly. A pendulum suspended from a high-quality bearing, oscillating in air, has a high Q, while a pendulum immersed in oil has a low one. Resonators with high quality factors have low damping so that they ring longer.
The definition of Q factor in the dictionary is a measure of the relationship between stored energy and rate of energy dissipation in certain electrical components, devices, etc, thus indicating their efficiency. Other definition of Q factor is Also called: Q value. the heat released in a nuclear reaction, usually expressed in millions of electronvolts for each individual reaction Q.
