Basic Electrical Theory ELECTRICAL SYMBOLSELECTRICAL SYMBOLSTo read and interpret electrical system diagrams and schematics, one must bethoroughly familiar with the many symbols used. Once these symbols aremastered, most electrical diagrams and schematics will be understood withrelative ease.EO 1.14 Given a standard electrical symbol, IDENTIFY the component that thesymbol represents. The symbols will be for the following components:a. Resistor m. Fuseb. Capacitor n. Junctionc. Inductor o. AC voltage sourced. Relayp. Voltmetere. Contacts q. Ammeterf. Breaker r. Wattmeterg. Switch s. Relay operated contactsh. Transistor t. Potential transformeri. Rheostat u. Current transformerj. Diodev. Wye (Y) connectionk. Ground connections w. Delta (D) connectionl. Vacuum tube x. Light bulby. BatterySymbolsThe symbols for the various electrical components that will appear on electrical diagrams andschematics are shown in Figure 30.Rev. 0 Page 45 ES-01
