(20 points) In this portion of the laboratory we will use a simulated inductor with components shown in Figure P1-1. This simulated inductor has an inductance of Lg R,R,C lk 1M 330u 330kH (This is an incredibly high inductance that would be almost impossible to build using a core and windings!) 1000 HF 4.7k 1 Vc 1.5 V VI Figure P1-2 Series RLC Circuit The nominal internal DC resistance of the simulated inductor is 1 kQ. IO 1I CO + For the circuit of Figure P1-2, using the simulated inductor from Figure P1-1, the switch has been in the down (2) position for a long time. Using nominal component values. find the complete time response of the capacitor voltage, v.(t), when the switch is moved to the up (1) position at t second intervals between 0 and 180 seconds. Plot the time response for 0 s ts 180 seconds. (Note: You will add data to this plot in later parts.) Os.. Prepare a table of computed voltage values for 15 Is this response overdamped, underdamped critically damped? or b. (30 points) Construct the circuit of Figure P1-2. After reaching steady state with the switch in the down (2) position, move the switch to the up (1) position and record capacitor voltage ve every 15 seconds for three minutes. Additional observers should note the time and magnitude of any maximum and minimum voltages observed. Record the observed values next to the computed values from part (a). Add the observed data to the graph from part (a). Comment on differen ces. long as are present in this experiment, obtaining annoyingly long time. The following steps will achieve a near-steady state condition suitable for starting: state initial condition can take steady Note: With time constants as a an 1. Short both capacitors with jumper wires. 2. A few seconds before 1 0, pull the shorts across the capacitors. Capacitor voltage may slowly start to change, but the effect of moving the switch should be much more significant. c. (10 points) Add a 30 kQ resistor to the series resistance so the total is 34.7 kQ plus inductor internal resistance. Establish an initial steady state condition with the switch in the down (2) position. Move the switch to the up (1) position and record capacitor voltage every 15 seconds for three minutes. Add this data to your table of results and graph. Based on the graph, is this time response overdamped, underdamped, or critically damped?
