Simboli elettrici ed elettronici
Un simbolo elettrico è una piccola immagine utilizzata per rappresentare un dispositivo o funzione elettrica o elettronica. Sono anche noti come simboli di circuito o simboli schematici in quanto vengono utilizzati in schemi elettrici e diagrammi.
Alcuni simboli elettrici di base includono:
Fili
Diodi
Batterie
Trasformatori
Condensatori
Resistenze
Induttori
Fusibili
Interruttori
Transistor a giunzione bipolare
Relè elettromagnetici
Esistono molti simboli elettrici e di circuito utilizzati a livello internazionale. Sebbene siano in gran parte standardizzati (cioè gli stessi simboli elettronici vengono utilizzati in diversi paesi), si possono ancora trovare alcune differenze internazionali.
Di seguito è riportata una tabella dei simboli elettrici più comunemente utilizzati nei
