  2. Ampere-hour - Wikipedia

    en.wikipedia.org/wiki/Ampere-hour

    An AA size dry cell has a capacity of about 2,000 to 3,000 milliampere-hours. An average smartphone battery usually has between 2,500 and 4,000 milliampere-hours of electric capacity. Automotive car batteries vary in capacity but a large automobile propelled by an internal combustion engine would have about a 50-ampere-hour battery capacity.

  4. Digital current loop interface - Wikipedia

    en.wikipedia.org/wiki/Digital_current_loop_interface

    A digital current loop uses the absence of current for high (space or break), and the presence of current in the loop for low (mark). [1] This is done to ensure that on normal conditions there is always current flowing and in the event of a line being cut the flow stops indefinitely, immediately raising the alarm of the event usually as the heavy noise of the teleprinter not being synchronized ...

    Power-on hours (POH) is the length of time, usually in hours, [1] that electrical power is applied to a device. A part of the S.M.A.R.T. attributes (originally known as IntelliSafe, before its introduction to the public domain on 12 May 1995, by the computer hardware and software company Compaq ), [ 2 ]

  8. Ampere - Wikipedia

    en.wikipedia.org/wiki/Ampere

    The ampere is named for French physicist and mathematician André-Marie Ampère (1775–1836), who studied electromagnetism and laid the foundation of electrodynamics.In recognition of Ampère's contributions to the creation of modern electrical science, an international convention, signed at the 1881 International Exposition of Electricity, established the ampere as a standard unit of ...

  9. Zinc–air battery - Wikipedia

    en.wikipedia.org/wiki/Zinc–air_battery

    Low humidity increases water loss; if enough water is lost, the cell fails. Button cells have a limited current drain; for example an IEC PR44 cell has a capacity of 600 milliamp-hours but a maximum current of only 22 milliamps (mA). Pulse load currents can be much higher since some oxygen remains in the cell between pulses.
