1. Batteries power much of our modern mobile lifestyle. AA batteries are often rated in units of milliampere-hours (mAh). This unit is actually a measure of the charge that the battery contains, and may be converted directly to coulombs by the formula 1 mAh = = 3.6 C. How many coulombs of charge are contained in a AA battery rated at 1500 mAH?
2. Thirty-five coulombs of charge flow through a wire in 2 minutes. Determine the current in the wire.
3. If 2 mA of current flow in your mp3 player, how long will it take for 1C of charge to flow?
