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:
“If the current is right, one can drift to success.”
—Mason Cooley (b. 1927)
“I don’t see America as a mainland, but as a sea, a big ocean. Sometimes a storm arises, a formidable current develops, and it seems it will engulf everything. Wait a moment, another current will appear and bring the first one to naught.”
—Jacques Maritain (1882–1973)
“Phlebas the Phoenician, a fortnight dead,
Forgot the cry of gulls, and the deep sea swell
And the profit and loss.
A current under sea
Picked his bones in whispers. As he rose and fell
He passed the stages of his age and youth
Entering the whirlpool.”
—T.S. (Thomas Stearns)
