Common circuit diagram symbols (American symbols) 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 can vary from country to country, or engineering discipline, based on traditional conventions. Standards for symbols The graphic symbols used for electrical components in circuit diagrams are covered by national and international standards, in particular: EC 60617 (also known as British Standard BS 3939). There is also EC 61131-3 ? for learning logic symbols. JIC JIC (Joint Industrial Council) symbols as approved and adopted by the NMTBA (National Machine Instrument Builders Association). They were extracted from the Annexure of the NMTBA Specification EGPl-1967. ANSI Y32.2-1975 (also known as IEEE Std 315-1975 or CSA Z99-1975). IEEE Std 91/91a: graphic symbols for logic functions (used in digital electronics). This is referenced in ANSI Y32.2/IEEE Std 315. Australian Standard AS 1102 (based on a slightly modified version of EC 60617; withdrew without replacement with a recommendation to use EC 60617). The number of standards leads to confusion and error. [1] Symbols used are sometimes unique to engineering disciplines, and national or local variations to international standards exist. For example, lighting and power symbols used as part of architectural drawings may differ from symbols for devices used in electronics. Common electronic symbols symbols shown are typical examples, not a complete list.

In general, Ferro magnetic metals such as iron are used. The core has a high permeability and is used to limit the magnetic field. Center Taped The center taped transformer has divided its secondary winding into two parts with the same number of turns in each part. This results in two individual output voltages over two line ends. Used in right-hander circuits. Step on Transformer The No. of turns in secondary winding is more than that of primary winding. The output voltage is higher than input voltage. Used significantly in converters. Step Down Transformer The No. of bends in secondary winding is less than that of primary winding.
