The LC circuit in Figure P22.80 has a certain resonant frequency f_res. Match the following changes to this circuit with the effect they would have on f_res.

(a) Connect a second capacitor in parallel with C.

(b) Connect a second inductor in parallel with L.

(c) Connect a second capacitor in series with C.

(d) Connect a second inductor in series with L.
(e) Connect a second capacitor with the same capacitance in parallel with C and connect a second inductor with the same inductance in parallel with L.

(1) Increase f_res.

(2) Decrease f_res.

(3) No change in f_res.
