The Q factor equals 2 π times the number of oscillation periods required for the stored energy to decay to 1/e (≈ 37%) of its initial value. Damped and lossy RLC circuits with high resistance have a low Q factor and are wide-band, while circuits with low resistance have a high Q factor. And RLC or LC (where R=0) circuit consists of a resistor, inductor and capacitor, and can oscillate at a resonant frequency which is determined by the natural rate at at which the capacitor and inductor exchange energy. Current calculator limitations. If the rate of the reaction is completely temperature independent, it can be seen from the equation above that the resulting Q 10 will be 1.0. Use the code as it is for proper working. Der Q-Faktor beim Fahrrad bestimmt die Standbreite (engl. circuit has a stopband from 1KHz to 50KHz.
