Question

The average velocity of the electrons in a conductor carrying a current of 65.5 amp is 0.0153 inches per sec.what is the cross-sectional area of the conductor.

Answer 1

electron charge = e in coulombs

i = how many coulombs pass a point in a second

65.5 coulombs/second = e * electrons per unit volume * area *length they move in one second which is .0153 inched

I think I need the density of electrons in electrons per cubic inch
