Final answer:
Dashed lines, solid lines, and dotted lines are used in electrical drafting lines to show the number of circuits.
Step-by-step explanation:
Lines used in electrical drafting to show the number of circuits include dashed lines, solid lines, and dotted lines.
Dashed lines are often used to represent hidden or non-visible parts of a circuit.
Solid lines are typically used to depict visible and connected parts of a circuit.
Dotted lines are used to indicate connections that are not physically present, such as in transformers or across long distances.
