Abm voltage source multisim

Lab 6 RLC Circuits Name: _____________________________________ In this lab you will analyze resistors, inductors and capacitors circuits. You will make calculations and verify your results. You will vary the values to gain further understanding of the circuit 1. The circuit above shows a RLC series circuit that are connected across the voltage source 48V. Before t =0, currents and voltages in R, L, and C are zero. a. What is the value of R if the circuit is critically damped? b. What is the value of R if the circuit is overdamped (use the values of R critically and multiply or divide by 10)? c. What is the value of R if the circuit is underdamped (use the values of R critically and multiply or divide by 10)? 2. Calculate and fill in the next table. Case alpha overdamped underdamped Critically damped W0 Wd A1,B1,D1 Write the solution for IL(t), and Vc(t) Case IL(t) overdamped underdamped Vc(t) A2,B2,D2 Lab 6 RLC Circuits Critically damped 1. Build the circuits using Multisim and find and plot IL(t) and Vc(t). For the source use ABM voltage source (> place>component>controlled voltage source>ABM_Voltage) and set the value to 48*u(time). Go to Simulate>analyses>Transient analysis and set the initial time (0) and final time (5*alpha) then select the outputs that you want to see. Click simulate (at the bottom of the dialog box). Ccopy and paste, in the space below, the response that was obteneid for the cases underdumped, critically damped and overdamper. Lab 6 RLC Circuits You can save the results in a graph file or text file (CSV coma delimited that can be open with excel 2.

Do you think is possible to connect a current source instead the voltage source, explain your answer? 2. How are the maximum currents and voltages in these three cases? Lab 6 RLC Circuits In the circuit L=0.64H C=1 uF and I=-1.The initial voltage drop across the capacitor is 40V and the initial inductor current is 0.5 A a. What is the value of R if the circuit is critically damped? b. What is the value of R if the circuit is overdamped (use the values of R critically and multiply or divide by 10)? c. What is the value of R if the circuit is underdamped (use the values of R critically and multiply or divide by 10)? Calculate and fill in the next table.
