Circuit variable problem
Not what you're looking for?
A current of 1400 A exits in a rectangular (0.6 X 9.0)cm copper bus bar. The current is due to free electrons moving through the bus bar at an average velocity of v meters/second. If the concentration of free electrons is 10^29 electrons per cubic meter and if they are uniformly dispersed throughout the bus bar, then what is the average velocity of an electron?
