In Figure E6-1, which is the schematic symbol for an N-channel dual-gate MOSFET?

Diagram for question E6A10

Deep Dive: E6A10

The correct answer is B: 4. In Figure E6-1, which is the schematic symbol for an N-channel dual-gate MOSFET is 4. Symbol 4 represents an N-channel dual-gate MOSFET. For amateur radio operators, this is important for transistor knowledge. Understanding this helps when reading schematics.

Why Other Answers Are Wrong

Option A (2): Incorrect. Symbol 2 isn't N-channel dual-gate MOSFET - symbol 4 is. Symbol 2 is wrong. Option C (5): Incorrect. Symbol 5 isn't N-channel dual-gate MOSFET - symbol 4 is. Symbol 5 is wrong. Option D (6): Incorrect. Symbol 6 isn't N-channel dual-gate MOSFET - symbol 4 is. Symbol 6 is wrong.

Exam Tip

N-channel dual-gate MOSFET symbol in Figure E6-1 = 4. Think 'N'-channel 'D'ual-'G'ate = '4'. Symbol 4 represents an N-channel dual-gate MOSFET. Not 2, not 5, not 6 - just 4.

Memory Aid

N-channel dual-gate MOSFET symbol in Figure E6-1 = 4. Think 'N'-channel 'D'ual-'G'ate = '4'. Symbol 4 represents an N-channel dual-gate MOSFET. Important for transistor knowledge.

Real-World Example

In Figure E6-1: Symbol 4 is the schematic symbol for an N-channel dual-gate MOSFET. This symbol shows two gates on an N-channel MOSFET. This is the symbol - 4 for N-channel dual-gate MOSFET.
