Unformatted text preview: The change in electric potential encountered by the object (with charge q ) as it moves from A to B is Since W AB /q>0, it follows that V B V A <0 . Electric field lines points from regions of high potential ( V A ) to regions of low potential ( V B ) A positive charge accelerates in the direction of the electric field, i.e. from a region of high potential toward a region of low potential. A negative charge accelerates in the direction opposite to the direction of the electric field, i.e. from a region of low potential toward a region of high potential. q W q EPE q EPE V V V AB A B A B = = q EPE V Unit of V : volt (=J/C) V A ( high ) A B E q F r r = E q F r r = q q V B ( low ) Electric field lines...
