*Question G7A13:
Which symbol in Figure G7-1 represents a tapped inductor?*  

*Correct Answer is  A: Symbol 7*  

### AI Response: (may contain errors)  

In Figure G7-1, the symbols represent different electronic components. To identify a tapped inductor, we need to understand what a tapped inductor looks like in schematic form.

1. **Correct Answer: Symbol 7**
   - A tapped inductor is represented by a coil with an additional connection point (tap) along its length. This tap allows for a portion of the inductor to be used separately from the rest. Symbol 7 in Figure G7-1 shows a coil with a tap, which is characteristic of a tapped inductor.

2. **Why the Other Choices are Incorrect:**
   - **Symbol 11:** This symbol typically represents a transformer, which consists of two inductors (coils) with a core, often shown as two parallel lines. It does not have a tap on a single coil.
   - **Symbol 6:** This symbol usually represents a standard inductor or coil without any taps. It is simply a series of loops or a spiral line.
   - **Symbol 1:** This symbol often represents a capacitor, which is shown as two parallel lines (plates) and does not resemble an inductor at all.

3. **Useful Information:**
   - **Tapped Inductor:** A tapped inductor is used in circuits where different inductance values are needed from a single coil. The tap allows for flexibility in circuit design, such as in variable frequency oscillators or impedance matching networks.

Understanding these symbols is crucial for interpreting circuit diagrams and identifying components correctly in the Extra Class exam.
