Alkaline Battery - Current

Current

The amount of current an alkaline battery can deliver is roughly proportional to its physical size. This is a result of decreasing internal resistance as the internal surface area of the cell increases. A general rule of thumb is that an AA alkaline battery can deliver 700 mA without any significant heating. Larger cells, such as C and D cells, can deliver more current. Applications requiring currents of several amperes, such as powerful flashlights and portable stereos, will require D-sized cells to handle the increased load.

Famous quotes containing the word current:

    A reaction: a boat which is going against the current but which does not prevent the river from flowing on.
    Victor Hugo (1802–1885)

    It is not however, adulthood itself, but parenthood that forms the glass shroud of memory. For there is an interesting quirk in the memory of women. At 30, women see their adolescence quite clearly. At 30 a woman’s adolescence remains a facet fitting into her current self.... At 40, however, memories of adolescence are blurred. Women of this age look much more to their earlier childhood for memories of themselves and of their mothers. This links up to her typical parenting phase.
    Terri Apter (20th century)

    The first opinion that occurs to us when we are suddenly asked about something is usually not our own but only the current one pertaining to our class, position, or parentage; our own opinions seldom swim on the surface.
    Friedrich Nietzsche (1844–1900)
