				The circuit diagram is the language of electrical design and engineering. These diagrams are maps that anyone can read to see how to build the circuit. When engineers design or build any electrical circuit they either create a new circuit diagram or use an existing one. Interpreting circuit diagrams is an essential skill for electrical and many other types of engineer. Once built, these electrical circuits are used to light our houses, power computers, run cars, and pretty much every modern device that uses electricity.
