The total charge a battery can supply is rated in mA*h, the product of the current (in mA) and the time (in h) that the battery can provide this current. A battery rated at 1000 mA*hr can supply a current of 1000 mA for 1.0 h, 500 mA current for 2.0 h, and so on. A typical AA rechargeable battery has a voltage of 1.2 V and a rating of 1800 mA*h.
A) For how long could this battery drive current through a long, thin wire of resistance 28 Ω ?
