Homework Statement



An electric current of 6 A flows through a 5 mm diameter copper wire with a length of 10 m.
What is the average number of electrons that flow through a cross section of the wire per second?

Homework Equations



I=Q/t or I=dQ/dt Maybe, im not sure

The Attempt at a Solution


1 Coulomb = 6.24e18
6*6.24e18
3.744E19 e/s
