Which term best describes capacitors that are constructed with fixed plate geometry and protective covering?

• A. Transformer Theory of Operation
• B. Uses of Multiple Capacitors
• C. Fixed Capacitors
• D. Open Capacitors

Answer: (C)

When thinking about capacitor types, we categorize them by how their capacitance is set. Some capacitors have adjustable plates or moving parts, allowing the capacitance to be changed, while others have a fixed plate geometry and are packaged with a protective covering to shield the dielectric and plates and to protect against moisture and dust. The term that fits capacitors built with fixed plate geometry and a protective covering is fixed capacitors. Their capacitance value is determined by the fixed plate area and the spacing of the plates, and the protective covering provides insulation and mechanical protection, making them reliable for general use in circuits. The other options don’t describe a capacitor type. Transformer theory of operation relates to how transformers work, not to capacitor construction. Uses of multiple capacitors is a description of applications, not a type. Open capacitors isn’t a standard category for capacitor construction.
