Which symbol in Figure G7-1 represents a solid core transformer?
- A.Symbol 4
- B.Symbol 7
- C.Symbol 6 (correct answer)
- D.Symbol 1
WhySymbol 6 in figure G7-1 represents a solid core transformer. In figure G7-1, symbol 6 is drawn as two coupled coil windings separated by a small gap representing the transformer's core, the schematic convention for a solid-core transformer, answer C. Symbols 1, 4, and 7 represent other components in the figure, none matching that two-winding, gapped-core transformer symbol.
