A) To calculate the total charge, we can convert the mAH to coulombs. 1 mAH is equivalent to 3.6 coulombs, so the total charge the Google Pixel 7 battery is capable of running between its terminals is:
4355 mAH * 3.6 coulombs/mAH = 15678 coulombs
B) To calculate how many elementary charges this is, we need to know that 1 electron has a charge of approximately -1.602 x 10^-19 coulombs.
So, the total charge can be expressed as:
15678 coulombs / (-1.602 x 10^-19 coulombs) = 9.78 x 10^21 elementary charges
Therefore, the Google Pixel 7 battery is capable of running 9.78 x 10^21 elementary charges between its terminals.
A Google Pixel 7 has a 4355 mAH battery. (1mAH = 1 mA x Hour, meaning that a 1mAH device is capable of running a 1mA current for 1 hour.)
A) What is the total charge that the Google Pixel 7 battery is capable of running between its terminals?
B) How many elementary charges is it?
