Question

A tesla car needs to charge its 350-volt model and must send about 715 amps through its cabling to the battery. What is the rate of electron flow through the cable for the current involved?

Answer 1

One ampere is defined as $6.28\cdot10^{18}$ electrons per second. Therefore, rate of electron flow for the current of 715 amps is

$R=715\cdot 6.28\cdot10^{18}\approx 4.5\cdot10^{21}$ electrons per second.
