Your cell phone typically consumes about 300 mW of power when you text a friend. If the phone is operated using a lithium-ion battery with a voltage of 3.5 V, what is the current (in A) flowing through the cell-phone dirauitry under these circumstances? Compare your result with the data given in the table below. Typical Currents in Common Devices Device Current (A) Calculator 0.0001 Spark plug 0.001 0.003 iPhone (while charging) 60 watt conventional 0.5 lightbulb LCD television 1.9 1,800 watt hair dryer 15 O The current in the cell phone is greater than that in a calculator but less than that in a spark plug. O The current in the cell phone is greater than that in a spark plug but less than that in an iPhone (while charging). O The current in the cell phone is greater than that in an iPhone (while charging) but less than that in a 60 watt lightbulb. O The current in the cell phone is greater than that in a 60 watt lightbulb but less than that in an LCD television. O The current in the cell phone is greater than that in an LCD television but less than that in a 1,800 watt hair dryer.

Car batteries are usually rated in A*h (ampere*hours), which is a unit of charge. This rating tells us how much total charge the battery is capable of providing before it fails. The battery in Sam's new car is rated at 229 A*h. a) Determine the total charge that this battery is capable of providing. ____ C b) What maximum current does this battery provide in 31 minutes? ____ A
Car batteries are often rated in amp-hours. This rating indicates the quantity of charge that can pass through the battery before the battery's chemical energy must be restored by the car's generator or some other source. The amp-hour unit is convenient for simple calculations. For example, a 60-amp-hour battery can supply a current of 1.0 A for 60 h (or 60 A for 1.0 h) before going dead. Find the energy stored in the following. (a) a 56 A-h, 14 V car battery (b) a 1.1 A-h, 1.7 V flashlight battery
