_ Physics 211L RLC circuits Name: _Sarah Karam _ Section number: _1 _ Partner’s Name: _Farid El Braidy _ Instructor: _Ms. Sara Najm _ Calculate the resonance frequency from eq(3): 1 2 f LC π = = 10.38 Khz. A- Determination of the resonant frequency of an RLC circuit : i- DRB at 300 V in =10.0 V (peak-to-peak) Note that V in decreases slightly around resonance. You must adjust V in to 10.0 V at every measurement Frequency (Hz) Frequency (Hz) V out (V) f res – 7.0 kHz 3.78 0.46 V f res – 5.0 kHz 5.78 0.64 V f res – 3.5 kHz 7.28 1 V f res – 2.5 kHz 8.28 1.55 V f res – 2.0 kHz 8.78 1.9 V f res – 1.5kHz 9.28 2.3 V f res – 1.2 kHz 9.58 2.5 V f res –0.9 kHz 9.88 2.8 V f res –0.6 kHz 10.18 3 V f res –0.4 kHz 10.38 3.1 V f res –0.2 kHz 10.58 3.2 V f res 10.78 3.3 V f res + 0.2 kHz 10.98 3.2 V f res + 0.4 kHz 11.18 3.1 V f res + 0.6kHz 11.38 3 V f res + 0.9 kHz 11.68 2.8 V f res + 1.2 kHz 11.98 2.6 V f res + 1.5 kHz 12.28 2.4 V f res + 2.0 kHz 12.78 2 V f res + 2.5 kHz 13.28 1.9 V f res + 3.5 kHz 14.28 1.5 V f res + 5.0kHz 15.78 1.2 V f res + 7.0 kHz 17.78 0.9 V Plot the graph of V out versus frequency.
