Question

12. Which of the following accurately describes semiconductor diodes?

Answer 1

Answer;

D. Junction diodes are preferred over point-contact diodes for most purposes.

Junction diodes are preferred over point-contact diodes for most purposes; accurately describes semiconductor diodes.

Explanation;

-Semiconductor diodes are specialized electronic components with two electrodes called the anode and the cathode, that are made with semiconductor materials such as silicon, germanium, or selenium.

-Point contact diode is formed by touching a metallic wire with an N-type semiconductor to form a small area of contact.

-A p-n junction diode is two-terminal or two-electrode semiconductor device, which allows the electric current in only one direction while blocks the electric current in opposite or reverse direction. Junction diodes are preferred over point-contact diodes for most purposes.
