An Electronic Load is a device used to simulate electrical loads in testing and measuring circuits. It can absorb power from a power source, allowing engineers to evaluate the performance of power supplies, batteries, and other electrical components under various conditions. By adjusting the load, users can analyze how devices respond to different levels of demand. These loads can be programmable, meaning they can be set to change their resistance, current, or voltage automatically. This feature is particularly useful in testing scenarios where conditions need to be varied, such as in the development of renewable energy systems like solar panels or electric vehicles.
