Final answer:
Pictorial drawings do not show the physical details of electrical components as seen by the eye. Instead, they are used to represent the elements in a circuit diagram using lines and symbols. Schematics are two-dimensional representations of three-dimensional electric fields.
Step-by-step explanation:
Pictorial drawings do not show the physical details of electrical components as seen by the eye. Instead, they are used to represent the elements in a circuit diagram using lines and symbols. These drawings are called circuit diagrams or schematics, which are two-dimensional representations of three-dimensional electric fields.
For example, in Figure 20.3 (b) of the provided reference, a single schematic can represent different situations, such as a truck battery connected to a headlight or a small battery connected to a penlight. Schematics are useful because the analysis is the same for various circuit scenarios.
Therefore, the statement in the question is false - pictorial drawings do not show the physical details of electrical components as seen by the eye.
