Barometer A device for measuring pressure. Battery Electrochemical cells that transform chemical energy into electricity. Base In chemistry, bases are substances that, in aqueous solution, release hydroxide (OH −) ions, are slippery to the touch, can taste bitter if an alkali, [50] change the color of indicators (e.g., turn red litmus paper blue), react with acids to form salts, promote ...
This glossary of power electronics is a list of definitions of terms and concepts related to power electronics in general and power electronic capacitors in particular. For more definitions in electric engineering, see Glossary of electrical and electronics engineering .
A schematic representation of long distance electric power transmission. From left to right: G=generator, U=step-up transformer, V=voltage at beginning of transmission line, Pt=power entering transmission line, I=current in wires, R=total resistance in wires, Pw=power lost in transmission line, Pe=power reaching the end of the transmission line, D=step-down transformer, C=consumers.
A set of wiring diagrams may be required by the electrical inspection authority to approve connection of the residence to the public electrical supply system. Wiring diagrams will also include panel schedules for circuit breaker panelboards, and riser diagrams for special services such as fire alarm or closed-circuit television or other special ...
The International Electrotechnical Vocabulary (IEV) is managed list of terms and definitions organized by the International Electrotechnical Commission (IEC), which is grouped in classes. It serves to promote the global unification of terminology in the field of electrotechnology, electronics and telecommunications.
Brush Electric Company's central power plant with dynamos generating direct current to power arc lamps for public lighting in New York. Beginning operation in December 1880 at 133 West Twenty-Fifth Street, the high voltages it operated at allowed it to power a 2-mile (3.2 km) long circuit.
In electrical engineering, low voltage is a relative term, the definition varying by context. Different definitions are used in electric power transmission and distribution, compared with electronics design. Electrical safety codes define "low voltage" circuits that are exempt from the protection required at higher voltages. These definitions ...
