Which statement is correct concerning diodes?
A) Diodes are aligned to allow current flow in one direction only.
B) Diodes can be used to rectify DC voltages into AC voltages.
C) The stripe is on the anode side of the diode.
D) Normal turn-on voltage of a standard diode is 1.5 volts.

Question

Quizplus · Accepted Answer

Diodes are designed to allow the flow of current in one direction only, from the anode to the cathode. The reverse biased side of the diode has a high resistance and does not allow current to flow.

Answer: C 
 Diodes have a stripe or band to indicate the polarity of the diode. The stripe is typically on the anode side of the diode, which is the positive side.

Answer: D is incorrect as Normal turn-on voltage of a standard diode can vary based on the type and design of the diode. B is incorrect as Diodes can be used to rectify AC voltages into DC voltages, not the other way around.
