... CBSE Class 12 Physics Solved Question Paper 2016. 12. Quality factor relates the maximum or peak energy stored in the circuit (the reactance) to the energy dissipated (the resistance) during each cycle of oscillation. The mathematical representation is: Q = E stored /E lost per cycle. This document is highly rated by Class 12 students and has been viewed 106330 times. q factor derivation class 12: quality factor of low pass filter: how to calculate q factor rlc circuit: q factor for parallel resonant circuit formula: factorq: quality factor of antenna: value of quality factor: the q factor of a parallel resonant circuit is given by: • The quality factor increases with decreasing R • The bandwidth decreases with decreasing R By combining Equations (1.9), (1.10), (1.11) and (1.18) we obtain the relationship between the bandwidth and the Q factor.
