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:
““I” is a militant social tendency, working to hold and enlarge its place in the general current of tendencies. So far as it can it waxes, as all life does. To think of it as apart from society is a palpable absurdity of which no one could be guilty who really saw it as a fact of life.”
—Charles Horton Cooley (1864–1929)
“Without the Empire we should be tossed like a cork in the cross current of world politics. It is at once our sword and our shield.”
—William Morris Hughes (1864–1952)
“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)
