The above downloadable file contains the pre-built circuits corresponding to some of the experiments in the CSUS Electronics and Instrumentation Lab (Physics 115) course. This is a zip file. After downloading it to your computer, unzip its contents to any folder on your machine. For unzipping, you can can use any zip utility. Most likely, some zip utility is already available on your computer. If not, you can download any zip utility available on the internet (e.g., 7-zip). The unzipped individual circuit files will have the “.lab” file extension.

To load these circuit files, simulate them, and view their operation, you need to have ElectricVLab already installed on your machine.

To load a circuit file in ElectricVLab, you can use the Load My Circuit option under its File menu. Once loaded, you can interact with the circuit by changing the voltages, resistance values etc. Of course, you can also build your own circuits in ElectricVLab.
