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

Explanations & Calculations

• If that current flows through the cable then there would be 715 Coulomb's per second will be flowing.
• Then a manipulation with the charge of an electron, the rate can be found.

$\qquad\qquad \begin{aligned} \small R&=\small \frac{715\,Cs^{-1}}{16\times10^{-19}C\,electron^{-1}}\\ &=\small 4.5\times10^{21}\,electrons\,s^{-1} \end{aligned}$
