What is component 8 in figure T-2?

• A. Capacitor
• B. Battery
• C. Light emitting diode
• D. Variable inductor

Answer: (C)

The correct choice is a light-emitting diode (LED). In most circuit diagrams, components are identified with specific symbols. A light-emitting diode usually has a distinctive representation that indicates the direction of current flow, which is typically shown with an arrow and a line that represents the diode itself. LEDs are semiconductor devices that emit light when an electric current passes through them in the forward direction. They are commonly used in electronic circuits for indicators, displays, or signaling purposes due to their efficiency and bright output. In the context of component identification in circuit diagrams, recognizing the symbol that corresponds to an LED is crucial for understanding how the circuit will function and how to troubleshoot various electronic devices. Understanding the role and properties of an LED is essential for an amateur radio technician. It not only aids in identifying components on circuit boards but also is critical when designing or modifying circuits for radio devices. This knowledge can be specifically useful in projects involving visual indicators or lighting circuits within ham radio equipment.
