An electron has CHARGE not voltage.

It depends on how far you move it and the geometry of the conductors,

If you hang a medium-sized coin from a string, it might have a
picofarad of capacitance to the world. Since
Q = C * V
and Qe, the charge on an electron, is -1.6e-19 colombs, then if you
whack the coin with one electron, the change in voltage is negative
about 160 nanovolts. Numbers like that aren't impossible to measure,
so it's feasible that some science-project level of effort could
measure single electron charges using Mouser-type parts.
I repeat: you should take an elementary physics course and get
straight on basic stuff like this.

One electron is -1.6e-19 coulomb.
A colomb is not a volt, just like a quart is not a kilowatt. That'selectron, wouldn't there be a negative voltage of 1.6e-19 volt?
We've known this for ages.Your head is all screwed up, Radium.
He dislikes educating himself. Instead he prefers to ask stupid questions, adWhy don't you try reading a book on the subject?

One electron is -1.6e-19 coulomb. So if the coin is hit with one
electron, wouldn't there be a negative voltage of 1.6e-19 volt?
It would be 1.6e-19 volt divided by the coin's capacitance (to
ground) in farads.
Charge in a capacitor is voltage times capacitance. Voltage across a
capacitor is charge divided by capacitance.
If you want some good reading, I totally recommend my favorite physics
textbook, "University Physics" by Sears, Zemansky and Young. When I
was young, I often read that one when I had time to read, before I was
in highschool physics. Any edition is good. Libraries sometimes have it.

Good answer but not complete. Voltage is a measure of potential energy
and an electron can have as much energy as you wish if it is moving.
Your answer considers only the stationary charge component.

In the context of 'electronics basics' this raises
a discussion of capacitance.
I prefer, however, the universal context, and the most
common items in the universe are hydrogen and stupidity.
So, a difference of one electron to a hydrogen atom is
my answer, the familiar 'ionization potential', 13.527 volts.
I can't think, right offhand, of a stupidity-based answer.

I seem to recall an experiment by somebody named Millikan balancing oil
drops on a potential difference of several thousand volts. So, of course,
Wikipedia has an article on it, with pictures:
http://en.wikipedia.org/wiki/Oil-drop_experiment
(why remember anything these days?)
His experiment was fundamental in determining the charge on a single
electron, which is now thought to be
1.602176487(40) x 10?19
In order to generate a microvolt, that would need to be put on 1/6 of a
picofarad. So, your coin (which you measured later to be .4 picofarad) would
be high by a factor of 3. Maybe a dime would work?
BTW, how did you measure the capacitance of the quarter? It must be fun to
have all those cool toys laying around.
