Electrical device. Electric (al) devices are devices that functionally rely on electric energy ( AC or DC) to operate their core parts ( electric motors, transformers, lighting, rechargeable batteries, control electronics ). They can be contrasted with traditional mechanical devices which depend on different power sources like fuels or human ...
Circuit diagram. A circuit diagram (or: wiring diagram, electrical diagram, elementary diagram, electronic schematic) is a graphical representation of an electrical circuit. A pictorial circuit diagram uses simple images of components, while a schematic diagram shows the components and interconnections of the circuit using standardized symbolic ...
Measures current without physical connection. Curve tracer. Applies swept signals to a device and allows display of the response. Cos Phi Meter. Measures the power factor. Distortionmeter. Measures the distortion added to a circuit. Electricity meter. Measures the amount of energy dissipated.
Electrical switch. Earthing systems. v. t. e. A circuit breaker is an electrical safety device designed to protect an electrical circuit from damage caused by current in excess of that which the equipment can safely carry ( overcurrent ). Its basic function is to interrupt current flow to protect equipment and to prevent fire.
Electronics is a scientific and engineering discipline that studies and applies the principles of physics to design, create, and operate devices that manipulate electrons and other electrically charged particles. Electronics is a subfield of physics [ 1][ 2] and electrical engineering which uses active devices such as transistors, diodes, and ...
An electronic component is any basic discrete electronic device or physical entity part of an electronic system used to affect electrons or their associated fields. Electronic components are mostly industrial products, available in a singular form and are not to be confused with electrical elements, which are conceptual abstractions ...
The connection may be removable (as for portable equipment), require a tool for assembly and removal, or serve as a permanent electrical joint between two points. [2] An adapter can be used to join dissimilar connectors. Most electrical connectors have a gender – i.e. the male component, called a plug, connects to the female component, or socket.
The first US power plug and socket dated 1904. Several early American electrical plug and socket arrangements were invented by Harvey Hubbell. On 26 February 1903 he filed two patent applications featuring 2-pin plugs and adaptors for using his plugs with existing designs of lamp sockets and wall receptacles.
