Question 224Electricity/Electronics - 1st Asst/Chief70% to pass
Which of the listed devices may be used as a digital device?
AI Explanation
The correct answer is B) diode.
A diode is a semiconductor device that allows the flow of electric current in only one direction, making it a digital device. It can be used as a switching or rectifying component in electronic circuits, which is a key function in digital electronics.
The other options, A) variable choke, C) thermistor, and D) variable resistor, are analog devices that do not have the same digital switching capabilities as a diode. They are used for different purposes in electronic circuits, such as controlling the flow of current or sensing temperature changes, but they are not considered digital devices.
