Answer 1

A solid line with a solid circle at the end on electrical drawings indicates wiring for grounding.

Step-by-step explanation:

In electrical drawings, a solid line with a solid circle at the end indicates wiring for grounding. This symbol represents the connection between the electrical system and the earth or ground. It ensures the safety of the electrical system by providing a low-resistance path to the ground, preventing electrical shocks and protecting against electrical faults.
