🔍 Key Concepts

• Review standard electrical schematic symbols for inductors and transformers. • Consider what two short parallel lines drawn through or beside a coil usually mean in AC power circuits. • Think about how a fluorescent lamp ballast or transformer is typically built (air core vs iron/steel laminated core).

💭 Think About

• Look closely at components 3 and 5 in figure C: both involve coils. Ask yourself what added symbol is common to both and what physical feature of that device it might represent. • Eliminate options that don’t logically relate to a coil or transformer structure in an AC lighting circuit. • Consider which choice would affect the device’s magnetic properties rather than its electrical connection or mounting.

✅ Before You Answer

• Verify that the two parallel lines are drawn adjacent to, or passing through, the coil symbol rather than connected as a separate conductor. • Confirm that neither component 3 nor 5 is drawn as a ground symbol or chassis connection anywhere else in the diagram. • Ask which remaining option is commonly used to concentrate the magnetic field in inductors and transformers in power circuits.
