A capacitor's basic structure consists of 2 conductors, also known as the 'Plates', which are separated by a dielectric. The dielectric is made of electrical insulation materials such as paper, mica, ceramics, or air, etc. (See image) This is a description of a fixed capacitor.
The simplest form of capacitor diagram can be seen in the above image which is self-explanatory. The shown capacitor has air as a dielectric medium but practically specific insulating material with the ability to maintain the charge on the plates is used. It may be ceramic, paper, polymer, oil, etc.
The working principle of a capacitor is that it stores electrical energy in an electric field. It absorbs transients or spike voltages well. For instance, in the circuit diagram, a 0.1uF 630V Mylar or Ceramic capacitor is used. You will notice that the noise disappears. Capacitors are basic components.
The circuit symbol of a basic capacitor is shown in the below figure. The capacitor symbol is represented by drawing two parallel lines close to each other, but not touching. It consists of two terminals. These terminals are used to connect in the circuit. The ability of a capacitor to store electric charge is called capacitance.
The value of the capacitor is measured in terms of its capacitance value and is expressed in farads, microfarads, and nanofarads. 2. Voltage Rating Voltage rating is the operating voltage of the capacitor and it is measured in volts. 3. Temperature Co-efficient

Their structure and working principle are essentially the same as ceramic trimmer capacitors, but their movable and stationary plates are made of copper, and the dielectric between the plates is an organic film. Rotating the movable plate changes the overlapping area of the copper plates, thereby adjusting its capacitance.

Basically, a capacitor consists of two parallel conductive plates separated by insulating material. Due to this insulation between the conductive plates, the charge/current cannot flow between the plates and is retained at the plates.
The simplest construction of a capacitor is by using two parallel conducting metal plates separated through a distance by an insulating material.
