The above downloadable file contains the pre-built circuits corresponding to the experiments in the VTU Analaog Electronics Lab 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.

As an example, if you load the file “BridgeRectifierWithoutFilter.lab“, the view would look like what is shown at the beginning of the video below. ElectricVLab provides a visualization of the operation of the circuit. You can interact with the circuit by changing the voltages, resistance values etc. This can really help to deepen your understanding. You can also add/delete circuit elements or build your own circuits.

Some of the benefits you get from ElectricVLab are the following.

• Strengthening your understanding of electronics and supplementing what you read in your textbooks.
• As a preparation before actually performing the lab experiment in hardware.
• Before the lab exam at the end of the semester, you can visually go over all the experiments done over the semester by loading these files one by one on your computer.
