Question

Which of the following accurately describes semiconductor diodes?

A. Unlike point-contact diodes, junction diodes use a point of metal wire in contact with a single wafer of P-type or N-type material.
B. Junction diodes are preferred over point-contact diodes for most purposes.
C. Point-contact diodes are more likely to be used as rectifiers than junction diodes.
D. Unlike junction diodes, point-contact diodes are enclosed in a suitable casing and have terminals for connecting them to a circuit.

Answer 1

C is the answer if not I’m sorry but I came to the conclusion of C being the answer

Answer 2

The answer is A. Because it describes better a semiconductor diode

Step-by-step explanation:

A semiconductor diode is formed of a junction of P dopped material (excess of electrons), with a N dopped material (absence of electrons). Under the correct polarization, the electron flows from one side to another, other way electrons wont flow.
