A cell phone battery uses chemistry to create a charge separation between the terminals (anode and cathode). Such a battery is listed as having a capacity of Q = 5.5E-08 C. Part (a) How many free electrons does the battery contain, N? Part (b) If there are 1.0 million electrons moving through the phone every second how long will the battery last in seconds? Part (c) Current, I, is given in amps which are coulombs per second. What is the current passing through the phone?
