A body contact or body fault is a conductive connection between body and active parts of electrical equipment resulting from a fault. [1] A body, short or ground fault is: Perfect (direct) contact. If there is no fault resistance in the circuit Imperfect (indirect) contact. If a fault resistance is present in the circuit (e.g. wet branch, arc) [2]
The Systems Engineering Body of Knowledge (SEBoK), formally known as Guide to the Systems Engineering Body of Knowledge, is a wiki-based collection of key knowledge sources and references for systems engineering. [1]
Electronic engineering is a sub-discipline of electrical engineering that emerged in the early 20th century and is distinguished by the additional use of active components such as semiconductor devices to amplify and control electric current flow. Previously electrical engineering only used passive devices such as mechanical switches, resistors ...
A body of knowledge (BOK or BoK) is the complete set of concepts, terms and activities that make up a professional domain, as defined by the relevant learned society or professional association. [1] It is a type of knowledge representation by any knowledge organization .
Electrical telegraphy may be considered the first example of electrical engineering. [5] Electrical engineering became a profession in the later 19th century. Practitioners had created a global electric telegraph network, and the first professional electrical engineering institutions were founded in the UK and the US to support the new discipline.
Radio-frequency (RF) engineering is a subset of electrical engineering involving the application of transmission line, waveguide, antenna, radar, and electromagnetic field principles to the design and application of devices that produce or use signals within the radio band, the frequency range of about 20 kHz up to 300 GHz.
