Final answer:
Schematic diagrams and circuit diagrams are extensively used to show the arrangement of electric service equipment, with schematics providing a versatile representation of a wide variety of electrical circuit situations.
Step-by-step explanation:
When arranging electric service equipment, the most common tools used are schematic diagrams and circuit diagrams. Schematic diagrams are instrumental in visualizing the main aspects of an electric circuit. For example, they can depict various situations such as a truck battery powering a headlight or a small battery illuminating a keyhole, because the fundamental analysis remains the same across different applications. A schematic is composed of symbols like wires, represented by straight lines, batteries indicated by two parallel lines, and loads, typically shown with a zigzag to signify a resistor.
Circuit diagrams are drawn using lines and symbols to represent the conductive pathways and other elements, which are typically made from metals like copper in macroscopic circuits. These diagrams are essential for comprehending the electrical systems that power lighting and other electronics in buildings.
