Technical lettering. Technical lettering is the process of forming letters, numerals, and other characters in technical drawing. It is used to describe, or provide detailed specifications for, an object. With the goals of legibility and uniformity, styles are standardized and lettering ability has little relationship to normal writing ability.
History of discoveries timeline. Year. Event. 600 BCE. Ancient Greek philosopher Thales of Miletus described static electricity by rubbing fur on substances such as amber. 1600. English scientist William Gilbert coined the word electricus after careful experiments. He also explained the magnetism of Earth. 1660.
Electrical engineering is an engineering discipline concerned with the study, design, and application of equipment, devices, and systems which use electricity, electronics, and electromagnetism. It emerged as an identifiable occupation in the latter half of the 19th century after the commercialization of the electric telegraph, the telephone ...
Engineering notation or engineering form (also technical notation) is a version of scientific notation in which the exponent of ten is always selected to be divisible by three to match the common metric prefixes, i.e. scientific notation that aligns with powers of a thousand, for example, 531×10 3 instead of 5.31×10 5 (but on calculator displays written without the ×10 to save space).
Electrical engineering – field of engineering that generally deals with the study and application of electricity, electronics and electromagnetism. The field first became an identifiable occupation in the late nineteenth century after commercialization of the electric telegraph and electrical power supply. It now covers a range of subtopics ...
Electronic engineering. Printed circuit board. 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 ...
Electrical/Electronics engineering technology (EET) is an engineering technology field that implements and applies the principles of electrical engineering. [1] Like electrical engineering, EET deals with the "design, application, installation, manufacturing, operation or maintenance of electrical/electronic (s) systems." [2]
The Hawkins Electrical Guide was a technical engineering book written by Nehemiah Hawkins, first published in 1914, intended to explain the highly complex principles of the new technology of electricity in a way that could be understood by the common man. The book is notable for the extremely high number of detailed illustrations it contains ...
