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)
“This is no argument against teaching manners to the young. On the contrary, it is a fine old tradition that ought to be resurrected from its current mothballs and put to work...In fact, children are much more comfortable when they know the guide rules for handling the social amenities. It’s no more fun for a child to be introduced to a strange adult and have no idea what to say or do than it is for a grownup to go to a formal dinner and have no idea what fork to use.”
—Leontine Young (20th century)
“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)
