By convention, potential difference is defined as the [tex]\frac{W}{q_0}[/tex], where [tex]q_0 > 0[/tex] correct? When computing potential differences in my textbook, states in the derivation of the relationship that [tex]V_f - V_i = \[ \int_i^f E\dot ds\][/tex] by assuming a positive charge. From the relationships of potential and charge, seems if we used a negative charge, we would compute negative values of difference of potential in comparison to using a positive charge.(adsbygoogle = window.adsbygoogle || []).push({});

**that's a dot product in the integral. I don't know the LaTeX for a dot.
