Q1
What is a diode?
A diode is an electrical device that allows the current to flow only in one direction. In a circuit figure, a diode is denoted by a triangle with a straight line across one vertex.
Q2
What is the full form of the LED?
LED stands for Light Emitting Diode.
Q3
Explain the characteristics of an LED.
LED is a semiconductor light source that produces light when electric current flows through the diode. These diodes are widely used due to their effectiveness in terms of low power consumption, longer shelf life, and better illumination. There are various types of LEDs made and are classified into different categories.
Q4
What are the main types of LEDs based on current outputs?
Low-current LED, standard LED, and ultra-high-output LED are the main types of LEDs based on current outputs.
Q5
What are the uses of miniature LEDs?
Miniature LEDs are typically used in small electronic appliances such as calculators, cell phones, and remote controllers.
Q6
What is a Bi-colour LED?
Bi-colour LED lights are made of two light-emitting diodes in a single case. The wiring is inversely parallel, where one is in the forward orientation and another in backward, which makes one diode lit at one time. The current flow alternates between the two diodes, which results in colour change.
