.'d 44% 6:57 PM loncapa.hep.uprm.edu/res/upr2 Points:7 Due in 2 minutes In the figure is shown a LRC circuit with generator of alternating voltage of frequency f. The generator's voltage is Erms, the current of the circuit is Ir and the resonance frequency is fR. Which of the following statements, for the LRC circuit, is correct? L. For any f, Paveragerms If we set Ersthenms get its minimum value when f=fp. For any f, Paverage ms*Ems u) For any f, lrms-erms/R O If we set Erms then Irms get its maximum value when

Explanation / Answer

In a series LRC circuit, impedance is minimum at resonant frequency fR.

Hence at f = fR Impedance is minimum and Current is maximum.

Option (5) is correct.
