A
Ratio of energy stored per cycle to the initial energy
B
Ratio of energy dissipated per cycle to the initial energy
C
Ratio of energy stored per cycle to the energy dissipated per cycle
D
Ratio of energy dissipated per cycle to the energy stored per cycle
E

Solution:
Quality factor
It is defined as the
2
π
times the ratio of the energy stored in the system to the energy lost per period
i.e.,
Q
=
2
π
energy loss per period
energy stored in system
