Unformatted text preview: Lab 8 C.J. Gorrell Sinusoidal RLC Circuits EN ME350 0102 3/13/10 Picture 1 I. Objective To use PSpice to examine the sinusoidal steady state of a RLC circuit, as a function of frequency, as well as examine resonance in an RLC circuit. I I. Instruments Used A. PSpice B. Computer I I I. Series RLC Circuit A. Experimental Setup: Use the series RLC circuit below to plot the Voltage and Current magnitude and phase as a function of frequency, of the inductor. B. Data: Magnitude of Phasor Current Frequency 100Hz 10KHz 1.0MHz 100MHz 10GHz DB(I(V1))-100-50 Frequency 100Hz 10KHz 1.0MHz 100MHz 10GHz P(I(L1))-100d 0d 100d Phase of Current Magnitude of Voltage Across the Inductor Frequency 100Hz 10KHz 1.0MHz 100MHz 10GHz DB(V(L1:1))-200-100 100 Frequency 100Hz 10KHz 1.0MHz 100MHz 10GHz P(V(L1:1)) 0d 90d 180d Phase of the Voltage Across the Inductor C. Calculations: VAC 50cos(wt) Zeq R+j(-1/wc +wL) VL IwL I(w) Vs(w)/(((R^2+(wL-1/wc))^-.5)e^j(tan^-1((wL- 1/wc)/R)) Phase 0-(tan^-1((wL-1/wc)/R)) Resonance Frequency 1/(2pi*sqrt(LC)) Resonance Frequency 1.6MHz D.
