A hydrocarbon liquid that cools and insulates transformers and other types of electrical apparatus. transformer A static arrangement of conductors and possibly magnetic materials, that transfers energy by electromagnetic induction. transformerboard A kind of insulating paperboard used for internal structures of large oil filled power transformers.
Electric kettle: more than 90% [citation needed] (comparatively little heat energy is lost during the 2 to 3 minutes a kettle takes to boil water). A premium efficiency electric motor: more than 90% (see Main Article: Premium efficiency). A large power transformer used in the electrical grid may have efficiency of more than 99%. Early 19th ...
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.
The electrical energy input of this cell is 1.20 times greater than the theoretical minimum so the energy efficiency is 0.83 compared to the ideal cell. A water electrolysis unit operating with a higher voltage that 1.48 V and at a temperature of 25 °C would have to have heat energy removed in order to maintain a constant temperature and the ...

The glossary terms fit in the following categories in power electronics: Electronic power converters; converters, rectifiers, inverters, filters.
Energy efficiency may refer to: Energy efficiency (physics), the ratio between the useful output and input of an energy conversion process Electrical efficiency, useful power output per electrical power consumed; Mechanical efficiency, a ratio of the measured performance to the performance of an ideal machine
the energy efficiency category from A to G; the luminous flux of the bulb in lumens; the electricity consumption of the lamp in watts; the average life length in hours; According to the light bulb's electrical consumption relative to a standard (GLS or incandescent), the lightbulb is in one of the following classes: [15]
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 ...
