Answer to Question #210440 in Physics for Morgan Hopkin

Question

Sadie is holding onto a Van de Graff generator trying to get a shocking new hairdo.  By doing this, Sadie gets an excess of 6.4 x 1020 electrons.  What is the charge on Sadie?  If she holds on for 10 minutes what is the current running through Sadie.

Answer 1

The charge on Sadie

$q=6.4\cdot10^{20}\cdot1.6\cdot10^{-19}=102.4\ (C)$

The current running through Sadie

$I=\frac{\Delta q}{\Delta t}=\frac{102.4}{600}=0.171\ (A)$
