1 of 12 W ORCESTER P OLYTECHNIC I NSTITUTE D EPARTMENT OF E LECTRICAL AND C OMPUTER E NGINEERING EE2011—Introduction to Electrical and Computer Engineering AC Circuit Simulation Tutorial 1. Introduction . Read this entire document and follow every instruction it contains during your tutorial session. Doing so is the most effective way to ensure that you will complete the tutorial in the allotted time. In this laboratory project you will learn to use a circuit simulation software package known as Multisim. Multisim uses an industry standard simulation system known as PSPICE and wraps it inside a user-friendly graphical user interface. In later courses you will find that you can solve many problems that arise using Multisim, but, more advanced courses may require that you become familiar with the “text based” style of PSPICE in order to gain access to the higher degree of flexibility that can be obtained by bypassing the graphical user interface. You will use Multisim to construct and simulate an AC circuit in this lab. This will give you to opportunity to review notions of AC analysis and phasors. Multisim however can do much more: it can be used to solve DC circuits, transient circuits and circuits involving non-linear components magnetic coupling and logic devices. Remember: As usual, you must document all steps in your laboratory notes. These will be handed in to the laboratory TAs and Tutors at the end of the laboratory session. 2. Getting Started with Multisim Multisim has been loaded into most of the computers in the ECE department labs. Specificially, you will find it on all the computers in AK317a (your lab room for EE2011) and in the open lab: AK 120C. Begin by logging into the machine using your ECE password and the ECELABS domain.

2 To start Multisim, click the Windows “Start” button on the bottom left of the screen. On the pop-up menus click on "Programs" > "Lab Tools" > “Multisim 2001” and choose "Multisim 2001" from the submenu that appears. At this point you may be told that Multisim has to be installed. If so, go along with the installation until it finishes. When it finishes, it will produce a folder with Multisim contained in it. Double-click on this Multisim icon to finally launch the program. Once the program has been launched you will find the following window displayed on your screen, with an empty circuit drawing area. We will now construct our first simple circuit.

3 3 Experiment #1—Analyzing a simple AC circuit 3.1 Constructing the circuit On the left hand side of the window (shown above) is a vertical stack of icons that represent menus that we can open of components from which we can select to construct a circuit. The top most icon on the stack is the “sources” icon. If you hold your mouse cursor over this icon for a few moments without clicking, a label box will appear with the word “sources,” to help you identify it. Now click on the sources icon with your left mouse button. This click will generate a tall stack of sources from
