Hi ints remaining: 2 Feedback: 0% deduction per feedback. /) 50% Part (b) Calculate the total charge, in coulombs. of the electrons that pass through the calculator?Explanation / Answer
Solution) We have Charge Q=Ne
N is number of electrons
e is charge of electron
(b) Total charge Q=Ne
Here N is 8.1×10^(20)
e is 1.6×10^(-19)
Therefore charge Q=(8.1×10^(20)×1.6×10^(-19))
Q=12.96×10
Q=129.6 Coulombs
