What is a capacitance of a capacitor?
• A capacitor is a device that stores electric charge and potential energy. The capacitance C of a capacitor is the ratio of the charge stored on the capacitor plates to the the potential difference between them: (parallel) This is equal to the amount of energy stored in the capacitor. The E surface. 0 is the electric field without dielectric.

What does C C mean in a capacitor?
The capacitance C C of a capacitor is defined as the ratio of the maximum charge Q Q that can be stored in a capacitor to the applied voltage V V across its plates. In other words, capacitance is the largest amount of charge per volt that can be stored on the device: C = Q V (8.2.1) (8.2.1) C = Q V
What does a polarized capacitor symbol mean?
Polarized Capacitor Symbol The symbol of a polarized capacitor includes a straight line and a curved line. The curved line represents the negative terminal, often indicated with a minus (-) sign or a specific marking on the capacitor. The straight line represents the positive terminal, typically the longer lead on the physical capacitor.

What is a variable capacitor?
The capacitor consists of two plates; one is stationary, while the other is movable. This configuration allows the capacitor to provide a capacitance range from 10 pF to 500 picofarads. Some common types of variable capacitors include trimmers and turning capacitors. Here are some applications of the variable capacitors:
