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:
“Men perceive that equating love and domestic work is a trap. They fear that to get involved with housework would send them hurtling into the bottomless pit of self-sacrifice that is women’s current caring roles.”
—Debbie Taylor (20th century)
“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)
“But there, where I have garnered up my heart,
Where either I must live or bear no life;
The fountain from the which my current runs
Or else dries up: to be discarded thence,
Or keep it as a cistern for foul toads
To knot and gender in!”
—William Shakespeare (1564–1616)
