Which of the following is true about a diode?
A) A diode causes the voltage to shift in phase by 90°, i.e., a right angle.
B) A diode has high resistance in one current direction and low resistance in the opposite current direction.
C) A diode can only be used with a transformer.
D) All filter circuits contain a diode.
E) All of the above.

Question

Quizplus · Accepted Answer

A diode has high resistance in one current direction (known as reverse bias) and low resistance in the opposite current direction (known as forward bias). Option A is incorrect as a diode does not cause the voltage to shift in phase by 90°. Option C is incorrect as a diode does not require a transformer to function. Option D is incorrect as not all filter circuits contain a diode.
