Homework Statement
We have seen that a coulomb is an enormous amount of
charge; it is virtually impossible to place a charge of 1 C on an
object. Yet, a current of 10 A, is quite reasonable. Explain
this apparent discrepancy.
Homework Equations
I = nqvA
The Attempt at a Solution
i think it is because current is the amount of charge flow per second, and the amount of charge depends on the volume of the wire, hence current can be larger than the placed charges if volume of the wire is pretty big. is this a good answer? is there anything to add? thx
