*Question G7A09:
Which symbol in figure G7-1 represents a field effect transistor?*  

*Correct Answer is  C: Symbol 1*  

### AI Response: (may contain errors)  

In figure G7-1, you are asked to identify the symbol that represents a field effect transistor (FET). Let's break down the symbols:

1. **Correct Answer: Symbol 1**  
   - Symbol 1 is the correct representation of a field effect transistor (FET). FETs are typically depicted with three terminals: the gate, source, and drain. The symbol often includes an arrow on the source or drain to indicate the direction of conventional current flow.

2. **Why the other choices are incorrect:**
   - **Symbol 2**: This symbol usually represents a bipolar junction transistor (BJT), which has three terminals: the emitter, base, and collector. The arrow on the emitter indicates the direction of conventional current flow.
   - **Symbol 5**: This symbol is often used for a diode, which has two terminals: the anode and cathode. The arrow indicates the direction of conventional current flow.
   - **Symbol 4**: This symbol typically represents a capacitor, which has two terminals and is used to store electrical energy.

**Key Points to Remember:**
- FETs have three terminals: gate, source, and drain.
- The symbol for a FET includes an arrow to indicate current flow, similar to BJTs, but the configuration and terminal names differ.
- Recognizing the differences between FETs, BJTs, diodes, and capacitors is crucial for identifying circuit components correctly.
