Final answer:
The statement is true as fixed capacitors include types such as electrolytic, mica, ceramic, paper, tantalum, and polyester film, each chosen for specific electrical properties and uses in circuits.
Step-by-step explanation:
The statement that types of fixed capacitors include electrolytic, mica, ceramic, paper, tantalum, and polyester film is indeed true (A). Capacitors are essential components in electronic circuits, and they come in different forms each suited for specific functions. Electrolytic capacitors are known for their high capacitance and are characterized by an oxidized metal and a conducting paste. They should be used with caution as they are polarized and can be damaged if connected to a reverse voltage, such as an alternating current (AC) source.
Other types of capacitors such as mica, ceramic, paper, and polyester film are used based on their dielectric properties and the stability required for the application. The dielectric materials, such as mica, ceramic, paper, and Teflon, are used to separate the conducting plates of capacitors, influencing their overall capacitance and stability under various electrical conditions.
