Electrical Testing Simulator (ETS) is a simulator-based mobile learning application designed to help students measure voltages and test electrical components. This free educational tool is particularly useful for students taking online courses in electrical engineering or related fields. ETS can also serve as a valuable supplementary resource for instructors looking to enhance their course materials.

With ETS, users can engage in a variety of activities, including measuring wall outlet voltage, 12-V battery voltage, 9-V battery voltage, and 1.5-V battery voltage. The app also offers fuse continuity testing, diode continuity testing, and surface-mounted switch testing. The developers are continuously working on adding more activities to further enrich the learning experience.

It is important to note that ETS is completely free, providing users with unrestricted access to all activities. However, the app does display advertisements. The developers kindly request users to consider the following before giving a low rating due to the presence of ads: the app is a result of several months of development by a small team of individuals who aim to support students in their learning journey. Additionally, users have the option to remove ads through an in-app purchase, which would greatly support the developers.

Overall, Electrical Testing Simulator is a valuable tool for students and instructors alike, offering a simulation-based approach to learning and testing electrical components. Whether you are a student looking for hands-on practice or an instructor seeking to enhance your course materials, ETS provides a user-friendly platform to explore and understand electrical testing concepts.
