Which symbol in figure G7-1 represents a field effect transistor?

Diagram for question G7A09

Deep Dive: G7A09

The correct answer is C: Symbol 1. The symbol in figure G7-1 that represents a field effect transistor is Symbol 1. FET symbols show the gate, source, and drain, with the gate typically shown as a line perpendicular to the channel. For amateur radio operators, this is important for reading circuit diagrams. Understanding this helps when working with FET circuits.

Why Other Answers Are Wrong

Option A (Symbol 2): Incorrect. Symbol 2 represents a different component - likely a bipolar transistor or other device, not a FET. FETs have distinct symbols. Option B (Symbol 5): Incorrect. Symbol 5 represents a different component - likely a Zener diode or other device, not a FET. FETs have distinct symbols. Option D (Symbol 4): Incorrect. Symbol 4 represents a different component - likely a different device, not a FET. FETs have distinct symbols.

Exam Tip

FET symbol = Symbol 1. Think 'F'ET = 'F'ield 'E'ffect 'T'ransistor = 'S'ymbol '1'. FET symbols show gate, source, and drain with gate perpendicular to channel. Not Symbol 2, 4, or 5 - just Symbol 1.

Memory Aid

FET symbol = Symbol 1. Think 'F'ET = 'S'ymbol '1'. FET symbols show gate, source, and drain with gate perpendicular to channel. Standard FET symbol representation.

Real-World Example

You read a circuit diagram. Symbol 1 shows a field effect transistor with gate, source, and drain terminals. The gate is shown as a line perpendicular to the channel, which is characteristic of FET symbols. This is how FETs are represented in circuit diagrams.
