For a point charge,
$V\equiv-\int_C\mathbf{E}\cdot\text{d}\mathbf{r}=-\int_C\frac{-Q}{4\pi\epsilon_0r^2}\mathbf{\hat{r}}\cdot\text{d}\mathbf{r}=\frac{Q}{4\pi\epsilon_0r^2}\int_0^r\text{d}r'=\frac{Q}{4\pi\epsilon_0r}$

$V=-\int_C\mathbf{E}\cdot\text{d}\mathbf{r}=-\int_0^{r'}\frac{Q}{4\pi\epsilon_0r^2}\text{ d}r=\frac{Q}{4\pi\epsilon_0r}$

$V=-\int_C\mathbf{E}\cdot\text{d}\mathbf{r}=\frac{Q}{4\pi\epsilon_0R}-\int_R^r\frac{Q}{4\pi\epsilon_0r^2}\text{ d}r'=\frac{Q}{4\pi\epsilon_0r}$
where R is the radius of the sphere and r is the distance from the center of the sphere. Happy now? lrn2tex
