Answer Options

  • A) Symbol 2
  • B) Symbol 5
  • C) Symbol 1
  • D) Symbol 4

Correct Answer: C

Explanation

Symbol 1 is the representation of an N-channel Junction Field-Effect Transistor (JFET), which is a type of Field Effect Transistor (FET).

Field Effect Transistors (FETs), including JFETs and MOSFETs, are voltage-controlled devices, used widely as amplifiers or switches. Identifying this symbol is critical for understanding circuit diagrams, as the JFET has a specific gate, source, and drain configuration that distinguishes it from a bipolar junction transistor (BJT) like Symbol 2.
