Chapter 22, Problem 41P
The total charge a household battery can supply is given in units of mA · h. For example, a 9.0 V alkaline battery is rated 450 mA · h, meaning that such a battery could supply a 1 mA current for 450 h, a 2 mA current for 225 h, etc. How much energy, in joules, is this battery capable of supplying?

A battery can provide a current of 4.40 A at 2.00 V for 5.00 hr. How much energy (in kJ) is produced?
The charge (0.075 yC) stored in a component in your calculator is released and flows through a resistor in 1 millionth of a second (1 x 10^-6s) . Calculate the current that flows through the resistor and use it to calculate the resistance of the resistor. The calculator is powered by 4 AAA batteries in series, each 1.5 V, so the total voltage across the resistor is 6 V. Round your answer to the nearest tenth of an Ohm.
