G7A09
Which symbol in figure G7-1 represents a field effect transistor?
- A.Symbol 2
- B.Symbol 5
- C.Symbol 1 (correct answer)
- D.Symbol 4
WhySymbol 1 in figure G7-1 represents a field effect transistor. In figure G7-1, symbol 1 is drawn as a circle with a gate lead arrow pointing into a channel bar and no separate emitter arrow, the schematic convention for a field effect transistor, answer C. Symbols 2, 4, and 5 represent other components in the figure, none matching an FET's gate-and-channel construction.
