What type of electrical components consists of conductive surfaces separated by an insulator?

• A. Transformer
• B. Resistor
• C. Capacitor
• D. Inductor

Answer: (C)

The correct answer is the type of electrical component known as a capacitor. A capacitor is designed to store electrical energy in an electric field, and it consists of two conductive plates, or surfaces, that are separated by a non-conductive material known as a dielectric. This configuration allows the capacitor to accumulate charge when a voltage is applied across the plates. When an electric field develops between the conductive surfaces, the capacitor can store energy until the circuit requires it. The capacitance, or the ability to store charge, is determined by the surface area of the conductive plates, the distance between them, and the properties of the insulator used as the dielectric. Understanding capacitors is fundamental in many electronic and radio frequency applications, as they serve important roles in filtering, tuning circuits, and energy storage.
