What are Solar Panels and How Do They Work? Solar panels are devices that convert sunlight into electricity. They are made up of photovoltaic (PV) cells, which are usually made of silicon. When sunlight hits the PV cells, it excites the electrons in the silicon, causing them to flow and […]

What is Transistor Saturation? Transistor saturation is a state in which a bipolar junction transistor (BJT) operates at its maximum current capacity, with the collector-emitter voltage dropping to a very low value. In this state, the transistor behaves like a closed switch, allowing maximum current to flow through it with […]
