What is the meaning of electrical symbols?
Electrical symbols are a graphical representation of basic electrical and electronic devices or components. These Symbols are used in circuit and electrical diagrams to recognize a component. It is also called a schematic symbol. These components are represented by respective symbols for it.
What are the common electrical symbols?
Basic Electrical Symbols
- Ground or Earth. A ground symbol (IEC symbol 5017) identifies a ground terminal.
- Resistor. A resistor reduces current flow.
- Switch. Disconnects the current when open.
- Capacitor. A capacitor symbol shows two terminals running into plates.
- Fuse.
- Antenna.
- Inductor.
- Transformer.
