# Difference between volts and voltage and what signs to use?

The thing that is equal to electromotive force and potential difference is voltage.. right? And that is represented by a capital V?

And the thing that is joules/coloumbs.. That is a unit called volts? represented by.. a lower case v? Or are they both essentially the same..

I'm confused because on top of mixing E and V, I've also been introduced to a lower case cursive v today.. Thanks:)

A lower case v would mean instantaneous voltage.

Ahh.
http://science.howstuffworks.com/question501.htm
"The three most basic units in electricity are voltage (V)"
"Voltage is measured in volts"

So.. if V is voltage, what is volts in symbols?

Voltage is measured in volts, whose symbol is V.

So, just like if I wanted to say 50 newtons, I would right 50N..and if I wanted to say 50 volts, I would say 50V?

A lot of times, emf is represented by a script E to distinguish it from electric field
