Which statement about diodes is true? A) They can amplify electric signals. B) They consist of three layers of semiconductor materials. C) They allow the flow of current in both directions. D) They are known as unidirectional devices.
Understand the Problem
The question is asking for the identification of the true statement regarding diodes. It provides multiple options related to the functionalities and characteristics of diodes, and one of them is correct.
Answer
Diodes are known as unidirectional devices.
The final answer is that diodes are known as unidirectional devices.
Answer for screen readers
The final answer is that diodes are known as unidirectional devices.
More Information
Diodes are crucial components in electronic circuits, allowing current to flow in one direction only, thus acting as a one-way gate for current. They are not used to amplify signals, which is a function typically associated with transistors.
Tips
A common mistake is confusing diodes with transistors, which can amplify signals and consist of three layers. Diodes, however, only have two layers and do not amplify signals.
