A schematic is a simplified diagram that represents the elements of a system or process. It uses symbols and lines to show how different parts are connected or interact with each other. Schematics are commonly used in fields like electronics, engineering, and architecture to convey complex information in an easy-to-understand format. In electronics, for example, a schematic diagram illustrates the components of a circuit, such as resistors, capacitors, and transistors, along with their connections. This helps engineers and technicians visualize the design and troubleshoot issues effectively, ensuring that systems function as intended.
