Idea: the Q-factor tells how sharp the resonance is: Q=(ω₀L)/R, where ω₀ is the resonant angular frequency.
With ω₀=1/(√LC): Q=L/(R√LC)=1/R√L/C.
This contains L, C and R, and nothing about the frequency of the source.
So the Q-factor depends on the values of all three components L, R and C.
Reading this solution needs no sign-in. You only sign in to practise against the clock and keep your progress.
