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)
“It is a quite remarkable fact that the great religions of the most civilized peoples are more deeply fraught with sadness than the simpler beliefs of earlier societies. This certainly does not mean that the current of pessimism is eventually to submerge the other, but it proves that it does not lose ground and that it does not seem destined to disappear.”
—Emile Durkheim (1858–1917)
“The current of our thoughts made as sudden bends as the river, which was continually opening new prospects to the east or south, but we are aware that rivers flow most rapidly and shallowest at these points.”
—Henry David Thoreau (1817–1862)
