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 = 8.5E-08 C. Part (a) How many free electrons does the battery contain, N? N = Part (b) If there are 1.0 million electrons moving through the phone every second how long will the battery last in seconds? t = Part (c) Current, I, is given in amps which are coulombs per second. What is the current passing through the phone? I =
