Al, Carl said he forgives you. But just one more thing, why hasn't anyone given any thought about the poor forgotten angels and the lonely pin-head?? Sorry, the problem is I care too much about the feelings of others. Time for the meds. Later. Bruce (this is bifwynne, not Carl Sagan and not the pin-head)
How many electrons?
There is a lot of current between your amp and your speakers. Imagine that you are doing some normal listening to your favorite loud music, and consider the number of electrons that move between the amp output poles and the speaker cables every second, in either direction.
Among the following estimates for the number of such electrons, which one is the most accurate?
a) None
b) Between eighty seven and a thousand
c) Thousands
d) Millions
e) Billions
f) Trillions or more
It's OK to just guess, but if you want to use numbers, the unit of current is an ampere, which is a coulomb per second, and an electron has a charge of about
1.602176487(40)×10−19 coulombs.
