The image is a detailed diagram explaining the wiring of a lighting circuit, specifically focusing on the control of lighting with a pilot lamp (PL). It includes illustrations of the wiring setup when the light is off and on, showing the flow of electricity and the role of the pilot lamp. The diagram is labeled in Japanese, with sections explaining the operation of the pilot lamp and the overall lighting circuit. The post text humorously mentions that this type of wiring is something that must be memorized for exams but is rarely used in actual fieldwork, highlighting the disconnect between theoretical knowledge and practical application in electrical engineering.
