If $10^{9}$ electrons move out of a body to another body every second,how much time is required to get a total charge of $1 \, C$ on the other body?

What is the total charge of the electrons in a neutral atom?

In general,metallic ropes are suspended from the carriers that transport inflammable materials. The reason is:

When $10^{14}$ electrons are removed from a neutral metal sphere,the charge on the sphere becomes ...... $\mu C$.

While doing his experiment,Millikan one day observed the following charges on a single drop:
$(i)$ $6.563 \times 10^{-19} \ C$
$(ii)$ $8.204 \times 10^{-19} \ C$
$(iii)$ $11.50 \times 10^{-19} \ C$
$(iv)$ $13.13 \times 10^{-19} \ C$
$(v)$ $16.48 \times 10^{-19} \ C$
$(vi)$ $18.09 \times 10^{-19} \ C$
From this data,the value of the elementary charge $(e)$ was found to be:

Write the unit and value of the fundamental electric charge.
