👉 Schematics, also known as circuit diagrams or flow charts, are graphical representations of complex electrical circuits. They are used to show how different components in a circuit work together to achieve a particular function. Schematics can be drawn on paper or digitally and are often used for troubleshooting, problem-solving, and safety reasons. In schematics, the symbols represent physical objects such as switches, relays, resistors, capacitors, and other electrical components. They show how these components are connected together
