5 August 2013 UTC Re Parallel RLC circuit The following statement is meaningless This means that a wide band low Q circuit in one topology will become a narrow band high Q circuit in the other topology when constructed from components with identical values Of course it will if you convert from a Series to a Parallel tuned circuit you can not use the same value R The Series R will be a low value while the Parallel R will be a high value and the relation ship between them is Q squared 183 89 113 215 10 27
