🔍 Key Concepts

• Difference between a pictorial drawing and a wiring diagram • What a block diagram usually looks like (simple labeled boxes with functional names) • What a one-line diagram represents in power systems

💭 Think About

• Look closely at whether individual conductors and connections are shown as schematic lines, or whether the physical parts of the motor are drawn as they really look. • Ask yourself: does this illustration focus on electrical paths, or on identifying the physical components and their locations? • Consider which of the four choices is normally used when teaching the internal construction of a machine rather than its circuit connections.

✅ Before You Answer

• Verify whether the drawing shows realistic shapes of components like poles, frame, commutator, and armature, instead of just symbols or single lines. • Check if there are no separate boxes or simplified circuit symbols that represent entire functional groups (which would suggest a block or one-line diagram). • Confirm whether you can trace specific wires and terminals as a circuit, or if the diagram mainly labels parts for identification.
