Conceptual Physics

Electric potential of location in


field


V = PEe/qtest


V = electric potential


PEe = electric potential energy


qtest = test charge


Units: volts (V)


Electric potential around a point


charge


V = electric potential


k = Coulomb’s constant


q = point charge


r = distance from charge


What is the electric potential at


the location of the test charge?


V = PEe/qtest


V = (3.2×10í^16 J)/(1.6×10í^19 C)


V = 2.0×10^3 V = 2000 V
