What is component 6 in figure T-2?

Diagram for question T6C06

Deep Dive: T6C06

The correct answer is Capacitor. Based on the schematic diagram in figure T-2, component 6 is a capacitor, identified by its standard schematic symbol showing two parallel lines (plates) separated by a gap. Capacitors are passive components that store energy in electric fields and are used for filtering, coupling, timing, and energy storage. For amateur radio operators, being able to identify capacitors in schematics is essential for understanding power supply filters, RF coupling circuits, antenna tuners, and signal processing stages. Capacitors are among the most common components in radio equipment.

Why Other Answers Are Wrong

Option A (Resistor): Incorrect. Resistors are shown as zigzag lines or rectangles. Component 6 shows the capacitor symbol (two parallel lines), not a resistor. Option C (Regulator IC): Incorrect. Integrated circuits are shown as rectangles or boxes with multiple pins. Component 6 shows the simple two-plate capacitor symbol. Option D (Transistor): Incorrect. Transistors have three terminals. Component 6 shows the capacitor symbol with two terminals (one for each plate).

Exam Tip

Capacitors are shown as two parallel lines (plates). If you see two parallel lines separated by a gap, it's a capacitor. Resistors are zigzag, transistors have three terminals, and ICs are boxes with multiple pins.

Memory Aid

Capacitor = two parallel lines (plates). Think 'C'apacitor = 'C'onnected plates (two parallel lines). Stores energy between the plates.

Real-World Example

In a power supply schematic, component 6 might be a filter capacitor that smooths the DC voltage. This capacitor stores energy and releases it when the load demands current, maintaining stable voltage. Understanding capacitor symbols helps you identify filtering and coupling functions in circuits.
