Which of the following is accurately represented in electrical schematics?

Electrical schematics are logical maps of circuits designed to show exactly how components are electrically connected to one another. They use standardized symbols so engineers and technicians can easily trace the flow of current and signals. Schematics do not depict the physical layout, size, or appearance of the actual components, nor do they represent the physical lengths of the wires. A long line on a schematic diagram might represent a microscopic trace on a printed circuit board, proving that only the electrical connections are accurately represented.
