A capacitor is typically constructed as shown in Figure 5.1. When a voltage v is applied, the source deposits a positive charge q on one plate and negative charge –q on the other. where C is the constant of proportionality, which is known as the capacitance of the capacitor. Unit for capacitance: farad (F). two plates.
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
The schematic symbol of a capacitor, consisting of one straight line and one curved line that represent the plates, as shown in Figure 2b. Caption: a two plates capacitor made of conductive materials and separated by an insulator is showed in Fig. 2a, while commercial capacitors and schematic circuit are showed in Fig 2b.
The specifications of capacitors are: 1. Capacitance Value The value of the capacitor is measured in terms of its capacitance value and is expressed in farads, microfarads, and nanofarads. 2. Voltage Rating
Determine the relationships between charge, voltage, and stored energy for a capacitor. Relate the design of the capacitor system to its ability to store energy. Position the top foil strip one inch over the piece of paper (Note: do not let the pieces of foil touch each other!).
Capacitors are electronic components that store, filter and regulate electrical energy and current flow and are one of the essential passive components used in circuit boards.

but if resistance is made small, the water can run more freely. Once the water is running, it can be stopped by closing the valve. The water in the pipe, already in motion, must stop. When closing the valve very quickly, the water must stop flowing very quickly. The energy in the moving water suddenly has no place to go. In some plumbing systems, a distant "chunk" is heard when a …

Smaller capacitors, such as ceramic types, often use a shorthand-notation consisting of three digits and an optional letter, where the digits (XYZ) denote the capacitance in picofarad (pF), calculated as XY × 10 Z, and the letter indicating the tolerance. Common tolerances are ±5%, ±10%, and ±20%, denotes as J, K, and M, respectively.

For large capacitors, the capacitance value and voltage rating are usually printed directly on the case. Some capacitors use "MFD" which stands for "microfarads".
