Capacitor Guide: What is a capacitor?. I Classification and Function of Capacitors. A capacitor consists of two metal poles with an insulating material (medium) sandwiched between them. According to the structure, capacitor can be divided into fixed capacitor, variable capacitor, and adjustable capacitor.
Adjustable capacitors are very small capacitors, that are used as secondary capacitors. These are connected in series or parallel with fixed capacitors. If the adjustable capacitor is connected in series with a fixed capacitor then it is called a trimmer. If it is connected in parallel with a fixed capacitor then, it is called a padder.
Generally, capacitors are divided into two common groups: Fixed Capacitors; Variable Capacitors; Fixed Capacitors are those capacitors with fixed capacitance values. While Variable Capacitors have the variable (trimmer) or adjustable (tunable) capacitance values. Out of these the most important group is fixed capacitors.
