Electrical Engineering XYZ MCQs

The diode is best categorized as which type of device:

  1. Conductor
  2. Insulator
  3. Semiconductor
  4. None of the above

Correct answer: 3. Semiconductor

Explanation: A diode is a semiconductor device. Semiconductors are materials that have conductivity between that of conductors and insulators. In a diode, current can flow freely in one direction (forward biased) but is significantly inhibited in the other direction (reverse biased), due to the behavior of the semiconductor material and the structure of the device. This property allows diodes to be used in a variety of electronic applications such as rectification, signal demodulation, and voltage regulation. Therefore, the diode is best categorized as a semiconductor device.
