1. Laboratory Task Descriptions Verification of series RLC transient analysis computations For this laboratory exercise, students will construct an underdamped series RLC circuit, then make voltage and current measurements to investigate the validity of transient circuit analysis techniques for series RLC circuits. Measurements will be obtained using the oscilloscopes available in the laboratory. The signal generator will be used to apply a 0[V] to 10[V], 50[%] duty cycle square wave across the RLC circuit to establish the circuit response. The required square wave signal frequency for the RLC circuit will be computed below in part 2b of the prelab work. Note: To receive credit for the following prelab computations, all required equations for the prelab below must be generated in variable form before substituting component values. Generation of the equations in variable form is required to permit substituting the actual measured component values into the solution equations. This approach will improve the accuracy of the comparison between the theoretical and experimental values for the validation of the RLC transient circuit analysis. is(t) + Vs(t) ic(t) C + Vc(t) - iz(t) L 000 + VL(t) vi(t) ww i1(t) R1 Figure 1: RLC circuit to be used for verifying transient analysis (Assume R1 = 110[22], L = 10[mH], and C = 0.1[μF]) Prelab Part 2b: Signal generator frequency computations Note that each charge and discharge period for the inductor will require a minimum of 5t, so if we set the signal generator period such that each half-period is 10t, we will be able to see the entire charge and discharge process. Therefore, based on the time constant for the envelope associated with the underdamped RLC response computed in part 2(a) above, compute the signal generator frequency for the circuit shown in figure 1 such that the period of the square wave is 20t.
