OK. This may be a stupid question but here it goes. :D
When thinking about the measurement of current in Amperes how is the speed of the current factored in the equation?
Let me try to illustrate using example. Amperes is the measurement of the number if electrons or coulombs passing a given point in one second A = Q/t. However it seems to me that how fast those electrons are moving is missing in the equation.
Here's my (lame) illustration
I this wire at the marked point you have two electrons (coulombs) passing the marked point in one second. So the Amps = 2.
V
-------------------
o
o
-------------------
Now in this example you two electrons agaun but only one is passing the same marked point at a time. But... If they moved twice as fast in that same 1 second time frame you still can get Amps = 2.
V
-------------------
o o
-------------------
So the speed that the electrons are moving be factored somewhere in the equation?
Did I just qualify for a nobel prize? :) Or what am i missing
