What is component 6 in figure T-2?

• A. Lamp
• B. Capacitor
• C. Variable resistor
• D. Transformer

Answer: (B)

The correct answer is that component 6 in figure T-2 is a capacitor. Capacitors are essential components in various electronic circuits, serving to store and release electrical energy. They are used in filtering applications, coupling and decoupling signals, and timing circuits, among other functions. In the context of the figure, if component 6 is depicted with two terminals and is likely to have a cylindrical or rectangular shape, it suggests that it is indeed a capacitor, designed to store charge between its plates.

Understanding the function of a capacitor in a circuit can help in applying the knowledge effectively when analyzing radio equipment and other electronic devices. Capacitors can influence the electrical characteristics of a circuit, such as voltage and current behavior, and are crucial for tuning and circuit stability.

The other options, while useful components, do not fit the characteristics or application of component 6 as well as a capacitor does. For example, a lamp would be an indicator or output device that illuminates when current flows through, a variable resistor would alter resistance within a circuit for controlling current flow, and a transformer would be used to change voltage levels in an AC circuit. Each of these components performs a different role that doesn't align with the expected function of component 6 as it
