When an ac source of emf E = E_(0) Sin (100pit) is connected across a circuit, the phase difference between the emf E and the current I in the circuit is observed to be pi//4, as shown in the fig. If the circuit consists only of R-C(or) R-L (or) L-C series. Possible values of the elements of the circuit are
