Which type of capacitor is constructed from plates and dielectrics placed firmly together and covered with a protective material?

• A. Fixed Capacitors
• B. Variable Capacitors
• C. Improperly Installed Capacitors
• D. Open Capacitors

Answer: (A)

Fixed capacitors are built with two metal plates separated by a dielectric, and the whole plate-dielectric stack is held firmly together and enclosed in protective material. This solid, non-movable construction provides a stable capacitance and shields the components from moisture, dust, and mechanical damage. The description fits this type because it specifies a rigid assembly that’s covered for protection, which is exactly how fixed capacitors are designed. A variable capacitor changes capacitance by moving plates or adjusting overlap, which isn’t indicated here. The other two options aren’t standard capacitor types; they describe fault or condition rather than a construction category.
