Capacitor Circuit Diagram Symbol

The number is sometimes followed by a letter indicating that components are grouped or matched with each other e g.

Capacitor circuit diagram symbol. The unit of measure is the farad. Chapter 9 circuit schematic symbols pdf version a capacitor is a passive two terminal electronic component that stores electrical energy in an electric field. A capacitor is created out of two metal plates and an insulating material called a dielectric. A reference designator unambiguously identifies a component within an electrical schematic or on a printed circuit board the reference designator usually consists of one or two letters followed by a number e g.

Capacitors store electrical charge like tiny batteries. The metal plates are placed very close to each other in parallel but the dielectric sits between them to make sure they don t touch. Non polar capacitors do not have positive and negative leads so there is no wrong way to connect it in a circuit. There are hundreds of different types of electronic components and each has its own unique schematic diagram symbol.

An electronic symbol is a pictogram used to represent various electrical and electronic devices or functions such as wires batteries resistors and transistors in a schematic diagram of an electrical or electronic circuit these symbols are largely standardized internationally today but may vary from country to country or engineering discipline based on traditional conventions. In the schematic symbol the positive lead is represented by the plus sign. Fortunately you need to know only a few basic symbols and labels to get you started. Simple electronic circuits can have as little as two components.

Note that when used. Most electronic circuits will have additional components.
