Could anyone help me with this question? I don't know how to find the Potential Difference.
For example. It gives is say ( V is volts. Q is C - Culombs. E is J Joules)

V= ?
E= 45J
Q= 15C

I'm not sure how to solve this

You don't say what the situation is, but for potential difference we have the following relation:

[tex]V=\frac{E}{Q}[/tex]
 
yup

just do V = E / Q
 
That's what I don't get how to do. What do I do to find V?
Do I divide E by Q?
I'm sorry I'm really so bad at this ):
 
You get the potential energy of a charged particle by multiplying the charge with the potential at the place of the particle. If E is the potential energy of a particle the potential is E/Q.
