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 ...
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.
Direct current has many uses, from the charging of batteries to large power supplies for electronic systems, motors, and more. Very large quantities of electrical energy provided via direct-current are used in smelting of aluminum and other electrochemical processes. It is also used for some railways, especially in urban areas.
The word armature was first used in its electrical sense, i.e. keeper of a magnet, in mid 19th century. [3] The parts of an alternator or related equipment can be expressed in either mechanical terms or electrical terms. Although distinctly separate these two sets of terminology are frequently used interchangeably or in combinations that ...
The electrical resistance of a uniform conductor is given in terms of resistivity by: [40] = where ℓ is the length of the conductor in SI units of meters, a is the cross-sectional area (for a round wire a = πr 2 if r is radius) in units of meters squared, and ρ is the resistivity in units of ohm·meters.
