See their number is in the horizontal axis and alphabets in the vertical axis. A node is simply a filled circle or dot. The common elements in a wiring diagram are ground power supply wire and connection output devices switches resistors logic gate lights etc. This is the natural flow and it s the best way to read them. Pictorial wiring diagrams are easy to read when only a few components are involved.

Input output input output in case two or more connectors are connectedtothesamedevice markings indicating the same connectors are connected by a broken line. Add more components and the wiring diagram is harder to read. How ever a quick look at the pictorial at the right shows that more components. Read electrical wiring diagram. Circuit diagrams or schematic diagrams show electrical connections of wires or conductors by using a node as shown in the image below.

The box is marked with the numbers and alphabets followed by the page number. 10 the bulb switch plug and wire were easy to follow in the last diagram.
