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:
“But human experience is usually paradoxical, that means incongruous with the phrases of current talk or even current philosophy.”
—George Eliot [Mary Ann (or Marian)
“The English language may hold a more disagreeable combination of words than “The doctor will see you now.” I am willing to concede something to the phrase “Have you anything to say before the current is turned on?””
—Robert Benchley (1889–1945)
“A reaction: a boat which is going against the current but which does not prevent the river from flowing on.”
