Finding the electric and magnetic fields from a scalar potential?

Main Question or Discussion Point

E = - grad*phi - 1/c (dA/dt).
phi is the scalar potential, and is given. How do I calculate the vector potential = A ?
Is it A = (v/c) * phi ? If it is, then where is this equation coming from?
Thank you.

yeah, in any case, it is not possible to calculate the vector potential by only using the scalar potential and nothing else.
